I have repository with many branches and all source files have $Id$. When I change one file on trunk I have to change it also on specific branch from the same repository. If I simply copy modified file to specific branch and commit it then $Id$ will have new value. From this time the only difference between source file in trunk and source file in branch is value in $Id$ and file compare utilities will show it as difference.
Is there any way to have the same $Id in both trunk and branch?
