Yes, that's the tag that I mean.  Unfortunately, that command will 
abort if there are any files which don't have that version number 
(i.e. files added which aren't in the original distribution).  

The attached script reproduces the problem and the patch fixes the 
problem but I don't recommend that it be applied as is.  Although it 
fixes this specific problem, there are several places that 
RCS_tag2rev() will abort.  These should all be modified to return NULL 
instead of aborting.
