I do have some text sequences that are replaced by the SCM (Perforce in my case).
I do want to configure BeyondCompare to consider these sequences as unimportant differences in order to be able to ignore them when I compare files.
In my case it's about Python source files and the sequences are looking like
# $Id: //depot/.../filename#7 $
# $DateTime: 2010/09/01 10:45:29 $
# $Author: username $
# $Change: 1234 $
Sometimes these sequences can be outside comments, but even in this cases I would like to be able ignore these lines because they are not really changed.
