Not just at some point. The [revision] parameter there can go back in history
which is why I also put it here in the former mail:
git annotate configure.ac 34dd72a9^
005efcbe (Joseph Myers 2010-03-23 16:05:34 +0000 1022) tic6x-*-*)
fe571c9f (Joseph Myers 2011-04-28 13:24:51 +0000 1023) noconfigdirs="$noconfigdirs gdb sim"
005efcbe (Joseph Myers 2010-03-23 16:05:34 +0000 1024) ;;
It could be made more convenient but GIT provides IMO the best such
feature+performance so far to make it feasible.

ChangeLog is not usable for tracking such changes as I cannot trust it wrt
mistakes of its text vs. the real source changes. And also/primarily the word
description of the diff (*) there is too general.
(*) I do not understand why it makes sense to re-state by human what is already
present in the diff itself.

The problem with CVS is I need to access the server for anything. Which is
either slow or temporarily overloaded/inaccessible or I am just offline.
I would need to have always up-to-date rsync copy for local access - do you
have? It is just easier with GIT, and working even for projects where usually
the rsync access is not provided (but no other projects use CVS anymore).

Yes, that would be great.
