"""helper commands for Redmine to reduce the number of hg calls

To test this extension, please try::

    $ hg --config extensions.redminehelper=redminehelper.py rhsummary

I/O encoding:

:file path: urlencoded, raw string
:tag name: utf-8
:branch name: utf-8
:node: 12-digits (short) hex string

Output example of rhsummary::

    <?xml version="1.0"?>
    <rhsummary>
      <repository root="/foo/bar">
        <tip revision="1234" node="abcdef0123..."/>

        <branch .../>
        ...
      </repository>
    </rhsummary>
