fix: fix handling of merge commits by using overlayworkingctx
Most of this code was conceptually copied from what rebase does, with one small
difference: hgext.rebaserev.rebase uses branchmerge=True, while I had to use
branchmerge=False, or else it got really confused about updating to the same
revision in some situations. I believe that the difference is that rebase is
always dealing with *some* form of update - it never gets to mergemod.update if
the source and destination are the same, while we can encounter that situation
with fix. This may imply that this code has some issues with named branches that
should be investigated.

"""extend schemes with shortcuts to repository swarms This extension allows you to specify shortcuts for parent URLs with a lot of repositories to act like a scheme, for example:: [schemes] py = http://code.python.org/hg/ After that you can use it like:: hg clone py://trunk/ Additionally there is support for some more complex schemas, for example used by Google Code:: [schemes] gcode = http://{1}.googlecode.com/hg/ The syntax is taken from Mercurial templates, and you have unlimited number of variables, starting with ``{1}`` and continuing with ``{2}``, ``{3}`` and so on. This variables will receive parts of URL supplied, split by ``/``. Anything not specified as ``{part}`` will be just appended to an URL. For convenience, the extension adds these schemes by default:: [schemes] py = http://hg.python.org/ bb = https://bitbucket.org/ bb+ssh = ssh://hg@bitbucket.org/ gcode = https://{1}.googlecode.com/hg/ kiln = https://{1}.kilnhg.com/Repo/ You can override a predefined scheme by defining a new scheme with the same name.
