Karl/Catalin, et al,
Attached is my latest stab at StGit importing patches from compressed files. This
version doesn't try to differentiate by the file extension; it just tries to open
gzip or bz2 files and if those fail it reverts to text. I'm not completely happy with
it, but I've spent about as much time on it as I can afford to (for this week anyway).
Yeah, yeah, Karl, there are four new tests in t1800-import. Let me know if you think
there should be more (more for compressed input that is; I'm not crazy enough to sign
up to write more tests for *everything*). :)
