} Yuk. Could you see if there was a good reason for that?
The docs have this example:
To alter the default behaviour of file completion -- offer files
matching a pattern and directories on the first attempt, then all
files -- to offer only matching files on the first attempt, then
directories, and finally all files:
zstyle ':completion:*' file-patterns \
'%p:globbed-files' '*(-/):directories' '*:all-files'
This works even where there is no special pattern: _files matches
all files using the pattern `*' at the first step and stops when it
sees this pattern. Note also it will never try a pattern more
than once for a single completion attempt.
} If it is just for efficency it should perhaps be removed.
It appears to be done that way to intentionally short-circuit the process
exactly when %p is '*', so that (in the example above) no redundant group
'directories' is created when both files and directories are already in
the globbed-files group.
The correct behavior (which may be very tough to implement) would seem to
be to check the entire list of tags against the matcher style before the
loop begins, and bail at '*' only if there are no tags left with matchers.
