The various subtlties in what he could have meant was precisely what I
was trying to get a clarification of. (It seemed silly to wait for a
round trip delay before proceeding to the conversation.) It's not
clear what "use software to handle revision control" is meant to
suggest: is it that you could implement something at the resolution of
a typical editor undo buffer (individual character
insertion/deletions) or is it "you shouldn't need any finer resolution
than you can acheive with a current revision control system?".
Incidentally, to be clear I'm looking at things at the user experience
level: I don't care virtually at all about the difference between an
editor which has an accessible-within-the-editor built-in fine-grained
change buffer and one that acheives an accessible-within-the-editor
fine-grained change buffer provided by an external program. But for me
there's a huge difference between "to undo something on the current
buffer, repeatedly invoke the undo command in the editor" compared to
"open a terminal window, bring up a graphical rev control diff viewer,
find the revision id corresponding to the desired undo point, rewind
and check out that revision, go back to the editor and reload the
