   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.
