Date Tue, 03 Apr 2012 12:39:07 GMT
Author: jim
Date: Tue Apr  3 12:39:07 2012
New Revision: 1308863

URL: http://svn.apache.org/viewvc?rev=1308863&view=rev
Log:
Merge r1307067 from trunk:

Fix treatment of regex backreferences.

r904765 only made half of the necessary changes to remove the use
of '&' as an alias for '$0' and allow to escape any character with a
backslash.
