I'm using fossil to store documentation that I generate from LaTeX or other HTML generation systems.  I'm running into a few logical defects in how this is handled.  In this case, if I set the wiki to HTML, that should NOT apply to the tickets, that's just the wiki.  Wiki is in HTML and controlled by my crew, but tickets can come from any jerk on the internet.

So, tickets should stay wiki, and wiki can be either HTML or wiki.
