parser: add helper to reduce nesting of chained infix operations This will be used to avoid stack overflow caused by chained 'or' operations in revset.

convert: properly pass null ids through .hgtags (issue4678) Mercurial uses tags of null to mark deletions, but convert was silently discarding these because it had no mapping for them. Thus, it was resurrecting deleted tags.

commit: improve --close-branch documentation The confusion about whether this flag closes a whole branch or just a head comes up regularly on IRC, so add some clarification.

patch: add 'extra' argument to makememctx The uncommit command in evolve needs to create memory context with given extra parameters. This patch allows us to do that instead of always giving them an empty value and having to override it afterwards.

Therefore, 'path' ended up being relative instead of absolute.

repair: forbid strip from inside a transaction Stripping inside a transaction will (at best) crash or (at worst) result in very unexpected results. We explicitly forbid it early.

test-treemanifest: add globs for Windows

test-revert-interactive: don't escape the $ for $TESTTMP Otherwise, sh tries to exec the literal path '${TESTTMP}/editor.sh' on Windows. The test runs clean on OS X both with and without this change.

changelog: fix bug in heads computation This patch refactors the native computation of heads. It fixes a bug where filtered heads in the pending index could be returned by the native code despite their filtering.

changelog: change input type of index_get_parents We were wrongfully using int instead of Py_ssize_t for the revision number.

branch: don't warn about branches if repository has multiple branches already This warning exists to prevent git users from prematurely polluting their namespace when trying out Mercurial. But for repos that already have multiple branches, understanding what branches are is not optional so we should just shut up.
