PATCH: complete glob qualifiers following an equals expansion

[Oliver Kiddle <opk@xxxxxxx>]

It is valid and sometimes useful to put a glob qualifier on the end of
an equals expansion. Normally where globs apply, completion ends up in
_files or _path_files which is where completion checks for qualifiers.
But if the current word starts with =, _equal is used instead.

This patch adds similar code to _equal. I think any glob flag here would
be meaningless so have not replicated the _files code related to those.
