Hello Carlo,

You have trailing whitespaces in your patch, also your mailer wraps
lines. Please fix this before resending.

No () with return please.

This will only show the file completion when no suitable command is
found which is a bit strange behaviour. Normally I would expect to
see all possibilities. This can easily be archieved by calling both
command_complete() and file_complete() unconditionally.
