gzip: zless doesn't handle filenames with dollar signs correctly

[Paul Eggert]

Thanks for reporting the problem.  This is really a 'less' bug, not a
gzip bug, but I installed the following into upstream gzip to work
around the 'less' bug.

        * zless.in: Work around a bug in less 394 and earlier; it
        mishandles $%=~ in file names.  Problem reported by
        Sami Liedes in <http://bugs.debian.org/383358>.
