Angle brackets not being escaped/XSS vulnerability

[pbock]

Angle brackets are currently not being escaped in the generated HTML, which means that the title What could possibly go wrong with <insert x86 instruction here>? is parsed as HTML and shows up as What could possibly go wrong with ? in a web browser. This is of course undesirable.

Technically, this counts as an cross-site scripting vulnerability, although the potential for exploitation is very slim because the code only runs locally on one computer and the source of the data is semi-trustworthy.
