[resending to the proper list -- first one went to bug-grep] Finally, here is a long-overdue upstream-ready --rsyncable patch for gzip. I've Cc'd Rusty Russel, who is listed as the author. I'll push this in the next day or so, so any improvements people can suggest in the mean time would be most welcome. Most of the changes came from some distro patches (not sure if it was debian or fedora, since I began this long ago). I added the test, the NEWS blurb, a few comments and the commit log.
