paper, monoblue: link correctly to lines in annotate view
The links were to "foo#123" instead of "foo#l123". The gitweb and
spartan templates were already producing the correct links.
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.
