Comment:

 I think the behavior of least surprise is to treat "reserved" characters
 per RFC3986 as part of the URL *if and only if* it isn't followed by
 whitespace.  This is necessary but not sufficient, as what would happen
 with this URL would be surprising:

 http://www.google.com/?!

 The URL would be treated as "http://www.google.com/?" - since "!" is
 followed by whitespace.  However, did the user intend the URL to be
 "http://www.google.com/" followed by "?!" as punctuation?  Or, should both
 the "?!" have been part of the linked URL?

 This kind of "intention inference" is really tough.  I think there will
 always be cases where it "does the wrong thing" (not what the author
 intended) ...
