bugged (r2297 was repeating new and old header). By the way, I've also removed the replacement keywords. We were using them because it was a common usage with CVS but it is advised not to use them with Subversion. Personnaly, it is a problem when I search differences between 2 Piwigo installations outside Subversion. git-svn-id: http://piwigo.org/svn/trunk@2299 68402e56-0260-453c-a942-63ccdbb3a9ee
