Subject: clean/smudge filters on .zip/.tgz files
Message-ID: <20130226163800.454cd093@bigbox.christie.dr>

Various programs that I use ([Open|Libre]Office, Vym, etc) use a
zipped/.tgz'ed file format, usually containing multiple
(usually) plain-text files within.

I'm trying to figure out a way for git to treat these as virtual
directories for purposes of merging/diffing.  

Reading up on clean/smudge filters, it looks like they expect one
file coming in and one file going out, rather than one file
on one side and a directory-tree of files on the other side.

I tried creating my own pair of clean/smudge filters that would
uncompress the files, but there's no good way put multiple files on
stdout.

Has anybody else played with such a scheme for uncompressing files as
they go into git and recompressing them as they come back out?
