This commit also introduces a regression in that I decided that the best way to
avoid overly long and confusing names was to rename the current shell-*
switches to script-*, and have the shell command completion be
shell-completion.
renamed script-{completion,candidates} to shell-script-*
Updated docs with new switch names
Added -shell-completion switch to x11-repl and kitty-repl
Automatic reparsing of %sh{...}, while convenient in many cases,
can be surprising as well, and can lead to security problems:
'echo %sh{ printf "foo\necho bar" }' runs 'echo foo', then 'echo bar'.
we make this danger explicit, and we fix the 'nop %sh{...}' pattern.
To reparse %sh{...} strings, they can be passed to evaluate-commands,
which has been fixed to work in every cases where %sh{...} reparsing
was used..
Makes it easier for users who want to locate their kakrc file, and
does not require to go through shell expansion to get it as
"${XDG_CONFIG_DIR:-${HOME}/.config}/kak"
Fixes#1740
`autoload` is a reserved keyword in the ksh family of shells.
Some of these are common `/bin/sh` providers (e.g mksh).
Renaming it to have a prefix fixes autoloading on such systems (see #1353).
This should not have any side effects due to the limited scope.
* Kak relies on the kakrc file to be in ../share/kak/kakrc relative
to kak binary rather than in the same directory
* Added an install target to the Makefile
