Quoting problems with _zip (unzip) completer



Completing contents of zip files with metachars doesn't work,
completing actual files in a zip file that you have renamed also
doesn't work properly. These issues seem to be separate, but I could
be wrong. While hacking around in _zip it seems like I "fixed" at
least the first thing.

The most obvious example is:
% touch a b c
% zip test.zip a b c
% unzip test.zip <tab completes fine>a
% mv test.zip test\[.zip
% unzip test\[.zip <tab>
_zip:117: bad pattern: test[.zip(|.zip|.ZIP)
_zip:117: bad pattern: test[.zip(|.zip|.ZIP)
_zip:117: bad pattern: test[.zip(|.zip|.ZIP)

naming the file test[].zip which is a valid pattern simply doesn't
give any matches. Naming the files inside the zip file and calling it
test.zip fails in various ways, sometimes it just completes the last
file without giving a list, even though set -x shows the full file
list being passed to the completion system, and typing a partial name
+ tab completes that file. Mysterious.

The change I did that seems to solve the actual .zip file name issue is:

@@ -114,7 +114,7 @@ case $state in
     if [[ $service = zip ]] && (( ! ${+opt_args[-d]} )); then
       _wanted files expl zfile _files -g
'^(#i)*.(zip|xpi|[ejw]ar)(-.)' && return
     else
-      zipfile=( $~line[1](|.zip|.ZIP) )
+      zipfile=( $line[1](|.zip|.ZIP) )
       [[ -z $zipfile[1] ]] && return 1
       if [[ $zipfile[1] !=  $_zip_cache_list ]]; then
 	_zip_cache_name="$zipfile[1]"

i.e. remove the ~. I didn't test if this breaks completion if you
didn't type the ".zip" part of the filename. I've fiddled around
adding (q) and quotes everywhere but it doesn't seem to improve
matters any.
