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

zsh: complete users in ssh URLS

zsh: support remote cloning

zsh: add optional remote directory cache

sshrepo: fix the parsing of the ssh url

zsh: complete SSH directories

zsh: complete unknown commands normally

Check for at least having a final release of python 2.3.0 in setup.py Mercurial uses features that are not in 2.3a1.

test for git empty new files

git patch: create empty added files

zsh: tab-complete status results by directory Filter diff and revert for modified files only, unless -r is given.

filelog: rename filelog.size() to filelog.len() filelog.size() is misleading for users of revlog.size() since it doesn't return the size of the revision.

revlog: more nullrev fixes

revlog: return 0 as offset for nullid

doc: clone doesn't create a working directory in remote repos

revlog.size() fix handling of rev == -1

use workingcontext.files() to detect if the repo is unclean

allow update to switch to a different branch if the repo is clean

Explicitly use REVLOGV0 instead of 0 in bundlerepo.

Define and use nullrev (revision of nullid) instead of -1.
