Johannes Altmanninger 9c327b19a6 Fix extra or missing newlines at end of file in our fish scripts
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

# This function deletes a character from the commandline if it is
# non-empty, and exits the shell otherwise. Implementing this
