Yes, it looks like you're correct.  It seems that the completion code
decides if there are pattern characters present and if there aren't it
handles matching internally, so that it works.  Otherwise it passes the
whole thing to the pattern matcher.  (I haven't traced this through but
something like this must be happening.)

Hmm, I think this is quite tricky.  The pattern matcher doesn't know
about the matcher list and training it would be tricky.  Getting the
completion code to fix up fixed string parts of the completion is also
tricky.  So this probably needs documenting as a limitation for now.

 globbing, so it works not only for files but for any completion, such as
 options, user names, etc.
