debugindex: rename to debugindex debug-revlog-index
The command dump some content of the revlog index and omit a lot of
information. I am going to make it display the missing information.
For clarity, we rename the command to explicitly mention revlog.

"""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.
