In that case the two numbering schemes are functionally equivalent, and 
it becomes almost entirely a marketing issue.

... and at that point the proposed numbering scheme will be more hassle 
for Emacs developers than if Autoconf had stuck with the current scheme, 
because they'll have to alter the code in autogen.sh instead of merely 
changing AC_PREREQ(2.65) to AC_PREREQ(2.73) in configure.ac.


Anyway, it's not a big deal either way, and if you feel strongly about 
it then you're doing the work so you should get to decide.
