summary: run discovery only once for in/out against same repo Reuses the result of findcommonincoming if default and default-push are the same.

discovery: resurrect findoutgoing as findcommonoutgoing for extension hooks discovery.findoutgoing used to be a useful hook for extensions like hgsubversion. This patch reintroduces this version of findcommonincoming which is meant to be used when computing outgoing changesets.

transplant: remove unneeded loop over repo in revset

transplant: fix revset doc

mq: add a 'mq()' revset predicate that returns applied mq csets

pyflakes: ignore files marked no-check-code

revlog: compute correct deltaparent in the deltaparent function It now returns nullrev for chain base revisions, since they are conceptually deltas against nullrev. The revdiff function was updated accordingly.

changelog: fixes leaked file handle

setdiscovery: limit lines to 80 characters

subrepo: use code from 71ea5b2b9517 only if Python needs it (issue2795) With Python >= 2.6 the original code already works correct, therefore the fix for issue2556 on Python <= 2.5 broke relative subrepositories with newer versions of Python.
