dfcb37b3b6 Remove unused option normalization. 
This program only really accepts one short argument, `-h`, so this
extra complexity isn't necessary.

80edd464b6 Use explicit escaping for "\\n" newlines. 
Backslash is literal, so explicitly escape it rather than rely on
fallback behavior.

921afd7155 Prefix _debug strings with '•' to avoid highlighting bugs. 
GitHub's syntax highlighting doesn't work well when strings contain
function names with parentheses, so add character to the beginning of
the string to see whether this makes it better.

99b175f134 Add --auto-sudo option and expand option documentation. 
Using `sudo` within a script is generally considered poor practice, so
by default an error message is printed when the user attempts to perform
a write operation without sufficient permissions.

One way to deal avoid this error message is to alias `hosts` to `sudo
hosts`, but this then requires `sudo` for all operations and not just
write operations.

The new `--auto-sudo` option flag provides a way to automatically invoke
a write command with `sudo` when the user doesn't have write
permissions.

In order to provide cleaner documentation for this option, include more
option documentation in README.md.

149a51662e Handle blank arguments string when assigning to $_RAW_OPTIONS. 
When `$*` is specified with quotes and braces as `"${*}"`, a blank
argument array results in an error in older versions of bash. Remove
the braces to avoid this error.

187222614a Use braces in all variable references. 
Braces are only required in certain cases, but the cognitive overhead in
keeping track of which cases require braces can be reduced by simply
always using them.

Example: `${NAME}`

Retain more widely-used braces `$NAME` convention in documentation.

80a8e48c10 Use if..then in show to avoid non-zero exits. 
The `[[ ... ]] && ...` conditional style results in non-zero exits when
the test is false. Moving this to a traditional `if..then` style avoids
this behavior while also being more explicit about the objective of the
code. `|| return 0` or `|| exit 0` could have been added as an
alternative way to avoid the non-zero exit behavior, but is not used in
this case because the traditional `if..then` style is more common.

21069fb68d Add quotes around strings in list command argument tests. 
Quoting these strings more clearly communicates that these are not
variable or function names, and that the string itself is what is
being tested for.

09d6d83093 Fix --force behavior in remove. 
The `--force` option is passed to the function in `$_COMMAND_ARGV`,
which means that assigning arguments from positions in this array leads
to unexpected behavior depending on where in the argument list `--force`
is included. As a result, the `remove` function must parse the
arguments, removing the `--force` argument before assigning function
arguments to local variables.

a869da8e4e Clarify slicing example in $_COMMAND_PARAMETERS comment. 
The example assignment should have balanced quotes to avoid any copy /
paste errors or reader confusion. Remove the 'not' since it's clearer if
this is used as a parenthetical example of slicing.
