I do try and make the important ones like that stand out, but I can
understand how they could be missed easily enough.

Well, I was wrong anyway since hammiefilter did call mergefiles as well
(how the search missed that, I don't know).  I'll be more rigorous about
the cvs logs next time, promise.

Ah, I get it now, sorry - I should have read the diff more closely.
It's the code in is_boolean that fails.  I thought you meant code in the
is_valid test, which should work fine.  I'll check a fix in for this
ASAP.
