tarball support v0.3 Hello, I'm slowly improving support for tarballs in Mercurial. Attached patch is made against current tip in Matt's repository - f859e9cba1b9, and contains everything done so far. Changes: - gzip and bzip2 tarballs are sent immediately without writing to temporary files (I was wrong Matt, it can be done very easy) - hgrc customization, you can choose which type (if any) you will support There's no easy way to support compression levels, since TarFile open() assume that it is 9. I tried to use gzopen(), and bz2open() methods instead, but it seems that headers of generated archives, are missing or wrong. We could eventually try to rewrite tarfile.py and include our own version into Mercurial, but I don't know if it's good idea... Wojtek
