I don't have time to go digging on this at the moment, but the notes at this 
first URL are, I think erroneous in their description of the interpretation 
of the question mark (?) in regex.  Unless mod_rewrite is doing something 
non-standard with them.

The question mark, along with the asterisk (*) and plus sign (+) are the three 
main "quantifiers" in regular expressions.  They only affect the atom which 
immediately precedes them.  So, in the example on the iandoulas.com 
website, "abc?def.html" would match either "abcdef.html" or "abdef.html".

Excellent.  This is good stuff to know.  Honestly, I can't remember ever 
trying to create mod_rewrite rules with question marks in them before, so I 
was not aware of the issue.
