I didn't feel offended in any way, but reporting bugs that don't exist
is just counterproductive and a waste of time.

I already said that there might be problems if the URL contains quotes
or less-than/greater-than symbols in another mail . This can be fixed
by removing the first str_replace() (which I also proposed in the same
mail) or by repeating the second str_replace() for """, "'",
"<" and ">" (which might be even better from the perspective of
security). However, I don't think such URLs will be a common use case.
The second "bug" is expected behaviour, since punctuation marks at the
end of URLs shouldn't be included in the URL itself (imagine someone
putting a link at the end of a senctence). This is also how DokuWiki and
Flyspray behave. If there really is an URL requiring a punctuation mark
at the end of the URL (which there shouldn't be at all), this can be
remarked in the comment itself.
