Solaris awk at /usr/bin/awk is meant for backward compatibility with
an ancient implementation of 1977 awk in the original UNIX. It lacks
many features of POSIX awk. To use a standard-conforming version in
Solaris, one needs to explicitly use /usr/xpg4/bin/awk.
macOS awk is a variant of nawk, but it contains a unique patch for the
UTF-8 support. However, this patch causes the problem. If the input
contains any non-UTF-8 data, macOS awk stops processing and does not
do anything, instead of ignoring the unrecognized data and continue
the processing. However, the contents of the ssh configuration and
/etc/hosts is not under the control of fzf, so we cannot fix the input
when those files contain non-UTF-8 data. To work around this
behavior, one can set the locale to LC_ALL=C to treat the input data
with the plain 8-bit encoding.
And remove the short preview window for showing the whole command.
Because it is important to be able to see the whole command before
deciding to kill it.
Just like it’s already done for `_fzf_compgen_path()` and `_fzf_compgen_dir()`
allow a user to easily define his own version of `__fzf_list_hosts()`.
Also add some documentation on the expected “interface” of such custom function.

`__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] 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.

* [shell] exit immediately when called from non-interactive shell
The shell execution environment shouldn’t be modified at all, when called from a
non-interactive shell.
It shall be noted that the current check may become error prone for bash, namely
in case there should ever be a differentiation between `i` and `I` in the
special variable `-` and bash’s `nocasematch`-shell-option be used.

Take two.
* Avoid eval if the prefix contains `:=`
* This is not to evaluate variable assignment. e.g. ${FOO:=BAR}
* [zsh] Prevent `>(...)` form
* Suppress error message from prefix evaluation
* Stop completion when prefix evaluation failed
Thanks to @calestyo
* Explicitly specify the list of fields for consistent experience
* Add fallback command for BusyBox (Close#3219)
* Apply `--header-lines=1` to show the column header
Requires latest tmux built from source (e.g. brew install tmux --HEAD)
Examples:
# 50%/50% width and height on the center of the screen
fzf-tmux -p
# 80%/80%
fzf-tmux -p80%
# 80%/40%
fzf-tmux -p80%,40%
# Separate -w and -h
fzf-tmux -w80% -h40%
# 80%/40% at position (0, 0)
fzf-tmux -w80% -h40% -x0 -y0
You can configure key bindings and fuzzy completion to open in tmux
popup window like so:
FZF_TMUX_OPTS='-p 80%'
At the top of each zsh file options are set to their
standard values (those marked with <Z> in `man zshoptions`)
and `aliases` option is disabled.
At the bottom of the file the original options are restored.
Fix#1938
