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)

patchbomb: fix patch name generation in patch series

patchbomb: add tests for diffstat, inline, and attach options

patchbomb: make test markers more syntax highlighter friendly

graphlog: add assertion for allowed n_column_diff range

graphlog: drop redundant comment (see docstring)

patchbomb: extract a bunch of nested functions - clarifies dependencies on variables - extracts potentially useful utility functions - no need for separate confirm() function - error message style conformance - PEP 8 conformance

patchbomb: make `hg email` reusable for other patch sources Adds two internal options, patches and patchnames, which allow other extensions to email a given set of patches. The pbranch extension needs this to send its patches which are diffs between topic branches.

patchbomb: make options to email command reusable Makes the option set that controls the actual emailing of the patches available as patchbomb.emailopts.

Backed out changeset c5dbe86b0fee (issue1375)

inotify: fix replacing a folder with a file (issue1375)

fix test-export portability (issue1383) wc outputs with leading spaces on *BSD

merge with mpm

tests: fix test failures from default/template changes

tests: make killdaemons.py executable

hgweb: fix up the less/more links on the graph page Previously, they pointed to a non-intuitive revision, and got borked when using a URL-specified style combined with alternate revcounts.
