Hi,
tj@ just noticed that our RCS still doesn't know how to expand Mdocdate.
One consequence is that rcsdiff(1) shows wrong Mdocdate lines -
typically, for each revision, the ones from the previous revision.
That in turn causes cvsweb to show wrong Mdocdate lines in diffs.
I'm showing the patch here because RCS is still somewhat important
infrastructure.
OK?
Ingo
