localectl may emit an error for whatever reason. The localectl
completion runs localectl in a command substitution so our stderr
redirect doesn't apply. Just redirect to null. Hopefully this fixes the
tests.
New fish_indent does that too, so this will make any future reformatting
diffs smaller.
Done using either of:
perl -pi -e 'undef $/; s/\n*$/\n/' share/**.fish
kak -n -f '<a-/>\n*<ret>d' share/**.fish
