PATCH: compadd completion

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This will perhaps seem rather pointless because compadd is not exactly an
interactive command but I quite often write and edit small functions on the
command-line, especially now that vi-mode is working better. Also, this is
quicker than looking at the documentation for simple cases.
