When pulling from a non hg repository URL (e.g. http://www.kernel.org/hg)
you geta pretty obscure error (zlib: uknown compression type). The
attached patch modifies hgweb.py and hg.py to supply and check a
'Content-type: application/hg-0.1' HTTP header for the branches,
between and changegroup commands, so that we know it's a proper hg
repo before snarfing the input. Comments appreciated!
