stack: rename stack.revs into stack.indexedrevs They are accessible by an index, and are sorted. But they don't include all revisions for show in showstack().

stack: return from behindcount() early Reduces indentation.

stack: use self._revs in stack.behindcount() This code also doesn't care about the order of revisions, it just wants all revs except stack base, and that's what self._revs is.

stack: use self._revs in stack.heads() No code cares about the ordering of the heads anyway, so let's use the unordered property that doesn't need to be sliced (because it doesn't include base).

pick: Add a test to check that pick pick the right content

WIP on handling stacks

test: add a test for current behavior of precursors revset The precursors revset currently returns the closest predecessors of a revset. If these predecessors are not known locally, it returns an empty list.

obshistory: give a more correct name to a variable This variable holds a list of predecessors, which obslog presents to graphmod as parents so the latter could understand the data without the need to introduce another graph edge type specifically for predecessors. Also remove debug comments.

tests: unindent lines that only have one leading space One space is not even defined in our .t files syntax.

rewind: make __rewind-hash__ extra field be bytes

touch: make __touch-noise__ extra field be bytes

branching: merge with stable

evolve: fix some documentation grammar/typos

evolve: fix some documentation grammar/typos

changelog: mention the recent evolve improvements

tests: merge two tests about split changesets Because the removed test case is essentially already included in the succeeding one, the tests are merged by removing the first.
