Description of problem:
When you clone a bug that has attachments and file a new bug which includes the comments related to attachements, those comments in the new bug are not converted to hyperlinks.
For example bug #596300 is a clone of bug #539251. In both bugs there's a comment that says:
Created an attachment (id=372305)
In the original bug (539251) this is a link while in the cloned bug (596300) this is plain text.
IIRC this was not the case with previous versions of Bugzilla.
