Re: backslashes get stripped from $ signs

Looks like a problem with the blosxom renderer.  Templates use $ for
variables.  It allows you to escape the $ in a template with a \ so that
you can have dollar signs show up in templates.

However, it looks like render_template totally does this wrong by
changing \$ to $ after the variables have been expanded and affecting
the variable expansion values.  Thus any \$ get converted to $ in the
story body.

The code in the blosxom renderer that handles variable finding and
substitution is pretty complex.  Seems like it might be a good idea to
ditch that code, switch to using a real parser, and then we'd be able to
trivially fix this issue, too.  We'd also be able to add some other
features like if blocks.

I don't think that's something I want to do in 1.5, though.  This is
definitely a 1.6 issue.

In the meantime, you could add a second \ or patch your copy of the
renderer locally.
