tests: have a more elaborated test for _destrebase The previous repo had a single lineage and a single head, pretty boring for rebase related testing.

histedit: break _histedit function into smaller pieces We add _getgoal, _validateargs. This is a part of bigger effort to refactor histedit. Initial steps are to break _histedit function into smaller pieces which will supposedly be more understandable. After this is done, I will have a better understanding of how histedit works and apply that to fix issue4800.

automv: new experimental extension Automatically detect moves and record them at commit time. This extension was originally developed at https://bitbucket.org/facebook/hg-experimental

match: override 'visitdir' in subdirmatcher The manifest.manifest class has a _treeinmem member than one can manually set to True to test that the treemanifest class works as a drop-in replacement for manifestdict (which is mostly a requirement for treemanifest repos to work). However, it doesn't quite work at the moment. These tests fail: test-largefiles-misc.t test-rebase-newancestor.t test-subrepo.t test-subrepo-deep-nested-change.t test-subrepo-recursion.t All but test-rebase-newancestor.t fail because they trigger calls to subdirmatcher.visitdir(), which tries to access a _excluderoots field that does not exist on the subdirmatcher. Let's fix that by overriding visitdir() in a similar way to how matchfn is overridden, i.e. by prepending the directory before calling the superclass method.

run-tests: remove useless "failed" flag from addOutputMismatch() It never be set to True.

tests: load json with no fallback The json module should be available in Python 2.6 or newer.
