That's right. (The #q isn't needed though.)

Turns out that executables are added by using `compadd -k commands' so
it isn't filename based completion at all.

The only difference between _path_files and _files is that _files looks
up file-patterns. _path_files should only be used if there is a good
reason to disallow file-patterns.

Styles are there for adjusting things according to user preferences not
for fixing bugs in the underlying code. So the "annoyance" is not that
file-patterns or ignored-patterns can't handle this.

Yes that's true.

You can call the tag what you like. The value of file-patterns is a list
much like tag-order. It just happens that the default value includes an
all-files tag with the pattern *.
