merge with stable

evolve: update evolve merge message People are apparently unaware of --succ

import: fix the "is None" check for the Node We are checking the wrong variable.

test: remote "date" from the output of obsmarker meta Data is no longer a generic meta. it has its own field now.

test: adapt to mercurial changes Changeset 816be4ca4ae2 in core make hg config return non-zero when no value match the filter.

evolve: wrap setparents calls in begin/endparentchange Mercurial rev d259322a394b added a requirement to wrap any dirstate.setparents calls and their associated dirstate changes in begin/endparentchange.

merge with stable A couple of test fix were added on stable.

test: add glob annotations where Mercurial's run-tests.py suggests These happen to also be 5 of the 6 tests that warn about no result code when run on Windows. Probably not a coincidence. The tests previously warned about no result code whether or not it was run interactively. They only started working when test output changes were accepted in interactive mode, and these globs were added automatically.

evolve: really fix the 'grab' alias on Windows Something seems to have happened when importing cb36a4eb0157- it dropped the $@ argument to --rev, and it picked up a bunch of test changes for the obsolete sha1 replacement patch. Instead of backing it out and breaking the tests for the sha1 replacement, this just fixes the missing $@.

evolve: keep vague compatibility with 3.1 Matt Mackall work flow requires this to not crash in fire with 3.1. We apply basic bandage to stop the bleeding.
