When I upgraded my blogs this morning with subversion, I noticed that the response codes on just one of my blogs had something other that "U" at the beginning of the line:
$ svn sw http://svn.automattic.com/wordpress/tags/2.3.3/
U wp-includes/gettext.php
U wp-includes/version.php
U wp-includes/pluggable.php
G xmlrpc.php
U wp-admin/install-helper.php
Can someone tell me what this means? The rest of my blogs had U for every line. Thanks in advance.
