match: remove support for non-include patterns from includematcher
The includematcher will always get at least one include pattern and
will never get any non-include patterns, so we can remove most of the
code in it. This patch does mostly straight-forward deletions of
code. We will clean up further later.
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
http://docutils.sourceforge.net/
Use the Makefile in this directory to generate the man and HTML pages.
