rewind: alias the command to undo This is a step in unifiying rewind and undo and not talk about them as different commands or concepts. If there exists rewind command, that should be an alias of undo and the vice versa. The exact implmentation detail and how the command works etc. is a different thing but there should be just one command.

changelog: add a line about the usage of s# in evolve

caches: no longer warm the cache on strip in "auto" mode Before this patch, a strip would trigger a full and blind cache load that would include the stablerange cache. In repository like Mozilla this was a bit painful. The default "auto" mode now behave has intended.

evolve: use stack alias s# in `hg evolve` msgs As repository grows revision number lose their usefulness. To make it a little better than now, after this patch we will be using short stack aliases introduced by the topic extension (as displayed by `hg stack`). These stack aliases s# will be used only when user has enabled topic extension and his repo's current active topic is same as the revs to be evolved. For now, this patch doesn't cover `continue` case. I will discuss about this with Pierre-Yves David. Maybe we have to store the info in evolvestate that "we were using stack aliases".

evolve: extract displayer to _solveone() I extracted this displayer method to _solveone() so that it would be easy to pass a different template to show evolve msgs. In upcoming patches we will be using stacktemplate in some cases where we want to include stack alias s# in evolve msgs.

utility: add a template alias that will be used in evolve msgs This template use stack alias s# instead of rev number in messages printed when we run `hg evolve`. For example, this template's msgs will look like this: move:[s3] add aaa atop:[s2] add bbb move:[s4] add ccc I will be using this template in upcoming patches.

topic: add topicidx template keyword This keyword will be useful where we want to see the index of the changeset in the stack when we run `hg stack`.

changelog: fix version number

tests: update the test-topic.t with changes in core mercurial Yuya stabilized the -T option and now it's in help by default. CORE-TEST-OUTPUT-UPDATE: 0d703063d0c8

pullbundle: fix style warning

pullbundle: improves management of multiple branch while dealing with a head There were still case where a range was issued too early.

pullbundle: deal with head in a predicable order We use node order to make this repeatable from one clone to another. This is an arbitrary pick.

pullbundle: deal with another special case introduced by arbitrary ranges previous, we dealt with the case where the tippest subrange of the stable parent was too long. Now, we need to deal with the case where it is too small.

pullbundle: compat with Mercurial 4.7
