I've tracked down this problem down to the initial commit:

around line 745 of _path_files (currently), there is this code:

	if [[ -z "$listsfx" ]]; then
		[[ -n "$compstate[pattern_match]" ]] && SUFFIX="${SUFFIX:s./.*/}*"

this SUFFIX manglignt is required for:

$ ls u/s*/a[tab]	changes "/a" to "*/a*"

but it breaks
$ ls a/b/d/e/g[tab]	changing "/d/e/g" to "*/d/e/g*"

In both cases all the files ARE compadded properly, the problem emerges
from the leading and trailing asterisks added to the SUFFIX.

1. why the "*/d/e/g*" SUFFIX prevents completions from being used?
2. should it be left intact? What makes this *required* for u/s*/a?
3. if to be left intact - how to prevent this from happening? The only
difference I see are MATCH=/ MBEGIN=6 MEND=6.

The solution I've came works for me, but I got no idea why and if that's
even the rational way:

-	[[ -n "$compstate[pattern_match]" ]]			&& SUFFIX="${SUFFIX:s./.*/}*"
+	[[ -n "$compstate[pattern_match]" ]] && [ -z "$MATCH" ] && SUFFIX="${SUFFIX:s./.*/}*"

This code is full of hackery... "pws non-canonical hack", "A little
extra hack", "it should now be smart"...
