problems with RCS

[tr at lilly2.lab.fj.bapd]

Using "co", I checked out a source code file.  Then I modified it.
Checking it in with "ci" failed.  I got

	RCS/filename  <--  filename
	new revision: 1.3; previous revision: 1.2
	enter log message:
	(terminate with End-of-File or '.' RETURN)
	>> I changed the program
	>> .
	ci: diff failed
	ci aborted

diff failed?  Why?  How?  I have an RCS directory under my current
one.

Any ideas?
