Agreed.  Buuut... 1.4a-p1 seems wrong if HEAD is at 1.4c.  Worse, releasing 
1.4b-p1 sounds like it is related to 1.4b.  I still don't like it, and won't 
adopt it for libtool or m4.

I am aware of *very* few projects that can stick to this rule in practice.  
It is easy to contrive examples which cause this system to breakdown.

I'm okay with that, as long as we acknowledge that they really don't work 
in CVS.

So CVS will become 1.5a, and maybe you'll release 1.5b and change CVS to 
1.5c, and in the mean while you need a patch for the original 1.5, so you 
call that 1.6 (even though it is ``worse'' than 1.5a) and make change CVS 
HEAD to what? 1.6a?  And what number will the CVS branch that 1.6 came from 

I still think that a three point release number is infinitely cleaner in 
situations like this.

Alternatively, maybe you could increment the major number for releases along 
mainline, and the minor number for patch releases?
