Invoking fzf from an existing Vim popup terminal is a special case.
It requires some new code to avoid E994 from being raised and the user
being stuck in a non-closable popup window.
Fix#1916
Revert the change introduced in #552. It seems that the startup time
difference between bash and fish is not much of an issue now.

When we explicitly *pipe* $FZF_DEFAULT_COMMAND instead of making fzf
internally start the process ($FZF_DEFAULT_COMMAND | fzf), fzf may hang
if the input process doesn't quickly process SIGPIPE and abort.
Also, fzf#vim#grep temporarily swaps $FZF_DEFAULT_COMMAND instead of
setting 'sink' so fzf can kill the default command on 'reload'.

However, because of the "pipe conversion", the trick wasn't working as
expected.

We can go even further and always set $FZF_DEFAULT_COMMAND instead of
piping source command.
* Add MSYS2 support as a vim plugin
Add &shellcmdflag and TERM environment variable treatment.
- Make &shellcmdflag `/C` when &shell turns into `cmd.exe`
- Delete %TERM% environment variable before fzf execution
* Change shellescape default value depending on s:is_win flag
* Make TERM environment empty only when gui is running
* Stop checking &shell in fzf#shellescape function
This funcion's behavior is controlled by only if it is Windows or not.
So there is no need to check &shell.
* Take neovim into consideration when to set shellcmdflag
* Add &shellxquote control
In recent Nvim versions, an "Error running ..." message is shown even for normal
use cases, such as:
:Files
<c-\><c-n>
:close
Closing the window will :bwipeout! the terminal buffer, because fzf sets
bufhiden=wipe.
When deleting the terminal buffer while fzf is still running, Nvim sends SIGHUP.
This happens for quite some time already, but the bug only manifests since this
commit:
https://github.com/neovim/neovim/commit/939d9053b
It's The Right Thing to do when the application exited due to a signal.
Before that commit, no "Error running ..." message was shown, because 1 (instead
of 128 + 1 == SIGHUP) was returned which the exit handler in fzf.vim treats as
"NO MATCH".
IMPORTANT:
cmd.exe and powershell are fine in default Windows terminal.
cmd.exe prompt is broken on ConEmu because it natively supports ucs-2 only.
utf-16 support is exclusive to .Net (ie. powershell).
utf-8 supports requires chcp, external program, but does not fix the cmd.exe prompt.
Use powershell on ConEmu to avoid corrupted text on display
Previously a command like `echo a && echo b` would get transformed into
`echo a && echo b | fzf`, which only pipes the output of the second
command. Adding parentheses around the source command avoids this issue,
and works on both Unix and Windows.
