destutil: add new local variable to increase readability

Before this patch, local variable 'heads' is used not only for "all
branch heads" but also for "branch heads other than current parent".

This patch newly adds local variable 'otherheads' for the latter
purpose, to increase readability.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
