old scheme (False/None/0/'' == fail) made coding style
unnatural, did not allow use of mercurial commands as hooks.
new scheme (False/None/0 == pass) is pythonic, does not require peculiar
"return True" at ends of hooks, allows hooks like this:
[hooks]
# update working dir after push into this repo
changegroup.update = python:mercurial.commands.update
to write hook in python, create module with hook function inside.
make sure mercurial can import module (put it in $PYTHONPATH or load it
as extension). hook function should look like this:
def myhook(ui, repo, hooktype, **kwargs):
if hook_passes:
return True
elif hook_explicitly_fails:
return False
elif some_other_failure:
import util
raise util.Abort('helpful failure message')
else:
return
# implicit return of None makes hook fail!
then in .hgrc, add hook with "python:" prefix:
[hooks]
commit = python:mymodule.myhook
Some systems show "Thu Jan 01" instead of "Thu Jan 1", which breaks tests.
Using "1000000" yields "Mon Jan 12 13:46:40 1970", which looks the same on
all systems.

Add initial hook support
This adds the basic hook code as well as pre and post-commit hooks.
Argument passing is by environment variable key/value pairs so that
extra data can be passed over time. File lists will generally not be
passed to hooks as these can be extremely long (>1M).
