I regularly do the equivalent of:

grep PATTERN $(git ls-files | grep -v ChangeLog)

That is, in searches I typically ignore ChangeLog* files because of their 
less-useful chatter. I'd be happy if we stopped maintaining these files in the 
master branch (we should keep them for emacs-25). I'd be happy if we removed the 
existing ChangeLog* files from the master branch.

Even if we remove ChangeLogs, we should still have guidelines for commit message 
format, as saying "anything goes" would make it harder to read the output of 
'git log'. I don't mind using ChangeLog format in commit messages, as it's a 
well-understood format and switching to some other format could well be more 
trouble than it's worth.
