PATCH: completions for less, wiggle, merge, attr

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This is a few more completion functions: less I assume you've heard of.
merge is the RCS merge tool so has gone in _rcs. wiggle is similar but
patch based. Finally, there is completion for attr, setfattr and
getfattr which set extended attributes on files.
