I've checked in two minor changes to the upload form to the live code
(after they've been tested in HEAD):
1) The upload description is now multiline. It has always accepted long
input, it was just very cumbersome to enter. This is not meant to be a
substitute for a proper redesign of the upload form, just a quick hack
to encourage people to add proper summaries.
2) The issue where [[Category:]] tags and the like inserted in the
description would not be added to the database properly has been fixed
(by backporting the existing fix from HEAD).
Please report any problems in Bugzilla.
