Yes, the magic emacs comment at the end of the file allows emacs to auto-update 
the timestamp upon file save.  But hopefully the obvious '; # UTC' comment 
following the actual timestamp makes the intent clear even for non-emacs users.

How about the following?  To make sure I understand the branching rules 
correctly, I would simply apply this first to origin/branch-1-10, then merge 
that onto origin/master?

config.guess, config.sub, and texinfo.tex are pulled from elsewhere; 
additionally, their timestamps don't include hours (so the courser granularity 
reduces the likelihood of a timestamp moving backwards when two people edit the 
same script from different parts of the world within 24 hours).
