Where did the "bla" part come from?  Emacs didn't generate it, did it?
It's something you typed at some point, I guess?

More generally, would you please describe the steps in full detail,
including what you typed, exactly?

Also, what does ci.cmd say?  I'm not aware of any scripts in the RCS
distribution; 'ci' should be a program, i.e. ci.exe.  It could be that
what ci.cmd does has some relevance for this issue.

Thanks.
