`_path_files' does the matching itself -- and sometimes things get too 
hard for it.
To allow `-g ...' patterns, it has to append these patterns to the
string from the line and then use that to generate filenames. Now you
might say that with `-f', no pattern is really needed. If you change:

  f)     sopt="${sopt}f"
         pats=("$pats[@]" '*')
	 ;;

to

  f)     sopt="${sopt}f"
         pats=("$pats[@]" '')
	 ;;

and

  if [[ -z "$gopt" ]]; then
    sopt='-f'
    pats=('*')

to

  if [[ -z "$gopt" ]]; then
    sopt='-f'
    pats=('')

you get what you expected. The same could be done for `-/' (this is
left as an exercise to the reader). I don't want to produce a patch
for this, though, because if we change it, the behavior will differ
from the behavior you get with things like `-g "*.(tex|TEX)"'. Here
the `*' in the pattern makes in-word completion fail in the way you
described.
Maybe this is another entry to the list of things I suggested the
`compstyle' parameter for.

I'm not fully sure that I understand what you mean here. If you would
like to know if it possible to get a second key binding using the
completion code, but with `globcomplete'-behavior turned on, this is
simple:

- First solution: add a function

    _glob_complete() {
      compstate[pattern_match]=yes
      _main_complete
    }

  add a widget for it and bind that to a key. (Hey, you could get all
  this automatically by adding a file `_glob_complete' with the first
  line `#defkeycomp complete-word \C-xg' and the body above.)

- Second solution: modify your `_main_complete' by adding something
  like

    [[ $WIDGET = glob_complete ]] && compstate[pattern_match]=yes

  at the top. Then define a widget

    zle -C glob_complete complete-word _main_complete

  and that should do the job, too.

That's part of the things we are working on. I once had the idea to
make `compstate' get keys with the names of the options, but then
decided against it because some of them have multiple effects and I
wanted to do this in a cleaner way. Setting/resetting options in
cmpletion widgets, btw, will only seldom have an effect on the post-
processing, exactly for the reason, that this is now controlled by
`compstate'.
