Or one could preprocess the text directly before rendering it, e.g.:

aText = aText:gsub( '(`?)(<.->)(`?)', '`%2`' )
aText = markdown( aText )
aText = aText:gsub( '(`)(&lt;.-&gt;)(`)', '%2' )

That way anything between angle brackets is escaped.

Or at least this is what Nanoki, a wiki engine implemented in Lua,  
does to protect the innocent from shooting themselves in the foot :)

Try to edit the online demo:

In theory, functional anomalies aside, Nanoki's pages should always  
render as valid XHTML.
