When performing a \'svn merge\' from my development team\'s trunk into a branch, we occasionally experience merge conflicts that produce files with suffix names: *.mer
You performed 3-side merge diring conflict-resolving (when merging 2 different files). It this operation 3 sources used
r*** extension just added to the same filename in order to have 3 files on merge
After successful merging and marking conflict as resolved temp-files must disappear automagically, if my memory served me well
