When attempting to filter out the comment blocks on these test files, it also filtered out a line that it shouldn't have. It indicates that the files are identical.
I have attached the test files and jpeg files that show the details.
Bug was in regexp implementation of diffutils. WinMerge 2.8.* uses PCRE regexps which fixed lots of bugs like this.
However, your regexps don't work in 2.8.* either. Current implementation requires that regexp matches all lines in the difference, so you must match both | and - in the same regexp. Filtering comments is a bit tricky. :(
I'll close this bug as fixed, since the regular expression matching works. I'll work with line filtering improvements and allow matching single lines etc.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
