Comment (by amiller):

 I now have a regular expression that tests for an unescaped # in the furl.
 However I don't think it's complete. The regexp is {{{([\^\\\\]|^)#}}}
 which matches any # that is not preceded by a backslash.

 My test includes the following:
 {{{
         assert re.search(regexp, "test#test") is not None
         assert re.search(regexp, "#testtest") is not None
         assert re.search(regexp, "test\#test") is None
         assert re.search(regexp, "testtest") is None
 }}}

 Unfortunately I think the string {{{test\\#test}}} should probably be
 matched, but it isn't. I'd need to look at how the \-escaping works to be
 sure.
