I've spent some time on this now and I can reproduce the issue.
You've added a comment to issue #4155 but I am not sure if that is
really the same problem.
What is happening here is that your assumption to use svn:keywords
on a binary file conflicts with how the merge logic is currently
implemented. The merge logic purposefully skips keyword handling
on binary files entirely (see the detranslate_wc_file() function in
libsvn_client/merge.c), yet keywords are still expanded in the binary file.
This is inconsistent behaviour. But I'm not sure which way we should fix it.
I'm inclined to fix the merge logic to assume that binary files might have
keywords expanded. Fixing the inconsistency the other way, by preventing
keyword expansion in binary files in the first place, would be a more
invasive change and possibly be perceived as a regression by users (Neil
Any thoughts from others about this?
