Looking at it again, the problem is obvious: the - ? - is
used as a
non-greedy operator; it isn't supported in IE <6 at
least, and maybe
some versions of 6 from your testing.  It will also fail in
other older
browsers.

Prototype.js doesn't make much of an attempt to be
compatible with
older browsers, it requires modern versions of Gecko or IE
based
browsers, anything else will struggle.  I don't know whether
the
supported versions of browsers has ever been published, but
lack of
support for IE <6 appears to be known to some at least,
though I can't
find a document specifying the specific features that fail.
