Re: [PATCH] Drop dependency of dist target on ChangeLog

This looks good, except for the change to timezone/README:

It's awkward to have to paw through ChangeLog.old for version numbers, 
plus when I took the trouble to actually do that I found that the 
version numbers there were incorrect. So I propose the attached patch 
instead.

Subject: [PATCH] Update timezone/README

* timezone/version: New file, also taken from tzcode2018i.
* timezone/README: Reword so that people needn't paw through
old ChangeLog files to see which version we're using, a process
that is error-prone.  Update an obsolescent URL.
