and the precise symptoms of the bug:

Hello 

I am on Kubuntu Feisty, using RCS 5.7-18. The problem I report seems
also to happen in Xemacs 21.4.19 which makes me think that the problem 
lies in the RCS. 

I do the following:

emacs -q.
Open a new text file, test.txt.
Add 1 line register the file, execute vc-register.
Add a new line, execute vc-toggle. Now the modeline tells me I am in version
1.2 
co -p1 test.txt 
gives me as output the current file.
but 
co -p2 test.txt 
tells me revision 2 absent
I add a 3rd line and execute vc-toggle.

same result. 
co -p3 test.txt 
tells me revision 2 absent


Now I use (setq debug-on-error t)
vc-version-other-window

and I obtain an error message which I attach. The error is not surprising 
sind co did not return any version above 1!!!

under RCS, a revision number is never a simple integer.  there is always at
least one dot.  in the above tests, you may see results more consistent w/
your expectation if you use "-p1.2" and "-p1.3".  that is, the "1." is not
optional.

You are very right, with the exception of p1 instead of p1.1. I swore
that remembered that one should drop the
1. I just checked with GNU emacs and Xemacs, vc-version-other-window
   given the full version number like 1.3 works fine. 

Thanks very much and sorry for the silly mistake.
