} I use the _match completer, so "grep --*bin<TAB>" completes to
} "--binary-files=".  It doesn't match against descriptions though.

Unfortunately that doesn't help either, because the problem is that the
completion function didn't provide --binary-files as a possible match
in the first place.

The question is whether we can provide any useful help when a completion
can't find a match, sort of like the way Google suggests an alternate
query when your search turns up no pages.
