clone: fix updaterev to update to latest branch changeset (issue4528) Before this patch if clone --updaterev points to branch which head on src repo wasnt in dest repo, clone updated dest repo to default branch. After applying this patch, if changeset from src repo pointing at given branch is not in dest repo, it searches for changeset pointing for given branch locally in dest repo. Lookup in destination repo: 559: uprev = destrepo.lookup(update) is wrapped by try/except block to preserve current behaviour when given revset to -u is not found - it will not fail,but silently update dest repo to head of default branch.

revsets: makes follow() supports file patterns (issue4757) (BC) Before this patch, follow only supports full, exact filenames. This patch makes follow argument to be treated like file pattern same way like log treats their arguments. It preserves current behaviour of follow() matching paths relative to the repository root by default.

histedit: improve discoverability of edit commit message

revset: cache smartset's min/max As the content of a smartset never changes, min and max will never change either. This will save us time when this function is called multiple times. This is relevant for issue4782 but does not fix it.

spelling: behaviour -> behavior

glossary: fixup use of periods at end of entries * Include trailing period for entries * Move trailing period inside quotations for example sentences

histedit: fix grammar for help for safety aborts

revset: mark reachablerootspure as private

reachableroots: construct and sort baseset in revset module This can remove the dependency from changelog to revset, which seems a bit awkward for me.
