Hi!

Today I noticed that sometimes darcs generates strange patches:
http://re.jabber.ru/~alexey/ejabberd/_darcs/patches/20070829161259-9f22b-1bdefba7d07cdcbf79431c0e7de9e8a2ac4f7635.gz

Look at first hunks, they remove, and then add back the same lines:

hunk ./ChangeLog 1
-2007-08-29  Mickael Remond  <mremond@process-one.net>
-
-	* doc/guide.tex: Documentation for XML based optimisation build
-	time option (EJAB-298)

+	* src/mod_muc/mod_muc_room.erl: The mod_muc option max_users now

+2007-08-29  Mickael Remond  <mremond@process-one.net>

While I expected to see this:

hunk ./ChangeLog 1
+2007-08-29  Alexey Shchepin  <alexey@process-one.net>
+
+	* src/mod_muc/mod_muc_room.erl: The mod_muc option max_users now
+	limits max number of users in rooms and max_users_admin_threshold
+	sets a number of admin or owner accounts allowd to join after
+	max_users occupants
+

Am I missing something and this is an intended behaviour, or is it a bug?
Darcs version is 1.0.9~rc1-0.1 (from debian etch).
