update help on git diffs

zsh: make resolve with no options only complete unresolved files

mergetools: add pointer to the usual filemerge path

zsh: support for resolve

graphlog: fix regression with filelogs introduced by 7bc62ebe7693

Merge with crew-stable

convert: be even more tolerant when detecting svn tags Former code failed when tracking child directories we assumed were renamed with their parents but were really created in the tags directory. This happens in jQuery repository with /tags/ui/1.5b4/release@5455.

test-pull-branch: make it executable

graphlog: fix python2.3 incompatibility (used genexp, sorted())

keyword: move common code out of commit condition

lookup: fast-paths for int and 'tip'

doc: handle shortened command synopses

keyword: be more efficient about ctx usage

graphlog: kill whitespace from earlier refactoring

extensions: copy __module__ for wrapped commands

pull: update to branch tip if there is only one head on the current branch On pull, if the current named branch has only one head, update to it.

graphlog: use built-in log output buffering

graphlog: refactor common grapher code Extracts the column and edge determination code into a separate function usable on generic DAGs with at most 2 parents per node. grapher() is very similar to graphmod.graph(). I shall look into merging them when I try visualizing patch branches in hgweb. Started using contexts and renamed a bunch of variables (fewer underscores).

cmdutil: use change contexts for cset-printer and cset-templater

context: use descriptors to speed up lazy attributes

context: special-case changectx setup for integer changeid

Add contrib/perf.py for performance testing

lookup: speed up partial lookup

help: remove redundant 'hg <command>' from command synopses

revlog: speed up parents()

revlog: remove delta function

linkrev: take a revision number rather than a hash

patchbomb: add option to send intro email for a single patch (issue1120)
