1dbdb9438f [bash] Refactor access to "_fzf_orig_complete_${cmd//[^A-Za-z0-9_]/_}"
In the current codebase, for the original completion settings, the
pieces of the codes to determine the variable name and to access the
stored data are scattered.  In this patch, we define functions to
access these variables.  Those functions will be used in a coming
patch.

* This patch also resolves an inconsistent escaping of "$cmd": $cmd is
  escaped as ${...//[^A-Za-z0-9_]/_} in some places, but it is escaped
  as ${...//[^A-Za-z0-9_=]/_} in some other places.  The latter leaves
  the character "=" in the command name, which causes an issue because
  "=" cannot be a part of a variable name.  For example, the following
  test case produces an error message:

  $ COMP_WORDBREAKS=${COMP_WORDBREAKS//=}
  $ _test1() { COMPREPLY=(); }
  $ complete -vF _test1 cmd.v=1.0
  $ _fzf_setup_completion path cmd.v=1.0
  $ cmd.v=1.0 [TAB]
  bash: _fzf_orig_completion_cmd_v=1_0: invalid variable name

  The behavior of leaving "=" was present from the beginning when
  saving the original completion is introduced in commit 91401514, and
  this does not seem to be a specific reasoning.  In this patch, we
  replace "=" as well as the other non-identifier characters.

* Note: In this patch, the variable REPLY is used to return values
  from functions.  This design is to make it useful with the value
  substitutions, a new Bash feature of the next release 5.3, which is
  taken from mksh.

[fish] exit as well when called from non-interactive shell (#3467)
Just like with the other shells, exit fish to, if called from a non-interactive
shell.

We cannot use `return`, as older versions of fish (namely < 3.4.0) did not
support to use `return` in `.`-scripts (this was only added with fish commit
3359e5d2e9bcbf19d1652636c8e448a6889302ae).

Unlike in POSIX, fish’s `exit` is however documented to no cause the calling
shell to exit when executed in a sourced script (see:
0f70b2c0d3/doc_src/cmds/exit.rst (L20)
)

86fe40708b [bash] statically define __fzf_list_hosts() with either method
When bash-completion (and thus `_known_hosts_real()`) is / is not available this
will typically not change during the lifetime of a shell.

The only exception is if the user would unset `_known_hosts_real()`, but well,
that would be his problem.

So we can easily define `__fzf_list_hosts()` either using `_known_hosts_real()`
or using the old code, and avoid checking every time whether
`_known_hosts_real()` is defined.

If defined, use bash-completions’s `_known_hosts_real()`-function to create the
list of hostnames.
This obviously requires bash-completion to be sourced before fzf.

If not defined, fall back to the previous code.

f1d306feab [shell] move username prefixing code where needed
`__fzf_list_hosts()` seems like a function a user may want to override with some
custom code.
For that reason it should be kept as simple as possible, that is printing only
hostnames, one per line, optionally in some sorting.

The handling of adding a `username@` (which is then the same for each line), if
any, would unnecessarily complicate that for people who want to override the
function.
Therefore this commit moves that to the places where it's actually used (as of
now only `_fzf_complete_ssh()`).

This also saves any such handling for `_fzf_host_completion()`, where this isn’t
needed at all.

Right now it comes at a cost, namely an extra invocation of `awk` in the
`_fzf_complete_ssh()`-case.
However, it should be easily possible to improve `__fzf_list_hosts()` to no
longer need the final `awk` in the pipeline there.

[bash] Use command to “protect” further commands (#3462)
This commit causes all simple commands that are not built-ins or functions to be
invoked via `command` in order to protect them from alias substitution or from
accidentally taking functions of the same name.

It was decided to not “protect” `fzf` and `fzf-tmux` for now.
Maybe a better solution should be implemented for that in the future.

This orders and groups completed options and values in just as they appear in
the code respectively, for some option values, as they’d be printed in the
`--help`-output.

It does not add support for completion of `:` right after values that support an
optional `:some-further-value` postfix.
Neither does it add support for the `--option=value`-style.

Improve interactiveness checks (#3449)
* [bash] return instead of not executing an if-block, when non-interactive

This should keep the code more readable, be less error prone (accidentally doing
something outside the if-block and aligns the code with what’s already done for
zsh.

`0` is returned, because it shall not be considered an error when the script is
(accidentally) sourced from a non-interactive shell.

If executed as a script (rather than sourced), the results are not specified by
POSIX but depend on the shell, with bash giving an error in that case.

The shell execution environment shouldn’t be modified at all, when called from a

in case there should ever be a differentiation between `i` and `I` in the
special variable `-` and bash’s `nocasematch`-shell-option be used.

[bash] History, use perl if installed otherwise awk (#3313)
While awk is POSIX, perl isn't pre-installed on all *nix flavors.
This commit eliminates the mandatory dependency on perl by using awk
when perl is not available.

Related: #3295, #3309, #3310.

Test suite passed:
* `make error` all test sections 'PASS'
* `make docker-test` 215 runs, 1884 assertions, 0 failures, 0 errors, 0 skips.

Manually tested in the following environments:
* Linux amd64 with bash 3.2, 4.4, 5.2; gawk -P, one true awk, mawk, busybox awk.
* macOS Catalina, bash 3.2, macOS awk 20070501.

**Performance comparison:**

Mawk turned out the fastest, then perl.
One true awk's implementation should be the closest to macOS awk.
Test data: 230 KB history, 15102 entries, including multi-line and duplicates.
Linux, bash 4.4. Times in milliseconds.

| Command                 | Mean | Min  | Max  | Relative |
| :---                    | ---: | ---: | ---: | -------: |
| `mawk 1.3.4`            | 22.9 | 22.3 | 25.6 | **1.00** |
| `perl 5.26.1`           | 34.3 | 33.6 | 35.1 |   1.49   |
| `one true awk 20221215` | 41.9 | 40.6 | 46.3 |   1.83   |
| `gawk 5.1.0`            | 46.1 | 44.4 | 50.3 |   2.01   |
| `busybox awk 1.27.0`    | 64.8 | 63.2 | 70.0 |   2.82   |

**Other Notes**

A bug affects bash, which fails restoring a saved multi-line history entry as a single entry. Bug fixed in version 5.0.[^1]

While developing this PR I discovered two unsubmitted issues affecting the current perl script. The output stream ends with `$'\n\0000'` instead of `$'\0000'`. Because of this, the script does not deduplicate a duplicated entry located at the end of the history list; therefore fzf displays two identical (not necessarily adjacent) entries. A minor point about the first issue is that the top fzf entry ends with a dangling line feed symbol, which is visible in the terminal.
