Well, that's the problem. Which characters should belong to the end of
the URL, and which should not? There could also be cases in which
punctuation belongs to the URL. If punctuation is parsed as not
belonging to the URL, there would be no way to post a working link
to certain URLs. If punctuation is parsed as part of the URL, one could
insert a space between the URL and the punctuation that should not
belong to the URL. One should also consider that inserting an URL into
a sentence looks horrible and is normally not done (by me, at least).

About splitting at boundaries: Contrary to what I have said before,
using regular expressions seems to be a valid and efficient way.
(I thought you would have to escape tag-content and attributes in
different ways (percent-encoding vs. html-entities). After reading
the HTML4 specification I realized this is not the case, as content and
attributes are both escaped using html-entities)
