Add allowed bundle types as argument to hgweb unbundle capability. Arguments to capabilities were added before the 0.9.1 release, so there are no compatibility issues. Mercurial 0.9 didn't support http push. Using HG10GZ, HG10BZ and HG10UN has the advantage that new bundle types can be added later and the client doesn't have to try sending them first and reacting on errors sent by the server.

hgweb: remove debugging print

hgweb: introduce a new capability for sending a compressed bundle the header of the bundle is the same as a on-disk bundle HG10UN: uncompressed HG10BZ: bz2 HG10GZ: gzip no header means uncompressed (old client)

hgweb: if the server supports it, send a compressed bundle

Use httpconnection even with proxies. This should give us HTTP keepalive when we talk to proxies and should allow us to stream a file in unbundle (instead of reading everything into a string). This should fix issue376.

issue352: disallow '\n' and '\r' in filenames (dirstate and manifest)

hgweb: split URLs containing spaces or other escaped characters correctly

zsh: perform ~ expansion on _hg_root

mq: handle qpush -a with empty series

zsh: compute repository root instead of forking hg
