changelog: stop useless enforcing split at the end of transaction
Changelogs are no longer created inline, and existing changelogs are
automatically split. Since we now enforce splitting at the start of any write,
we don't need to enforce splitting at the end of the transaction.
This has the nice side effect of killing the only user of "side_write".

"""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.
