Re: michael/wjr merge

Just to let you know that some of us CroMags can read this stuff and
see red flags, here's a quick repartee to michael's quite informative

(Don't take any of this as flame... We ("the Montage crew") are caught
up in our own "front end battles" even so primordal that they're not
yet on group mailing.)

Whoa!  Some of us Neanderthals need to know from where you've diverged.
My starting point was alpha-5 (5/8/90) and if we're talking about "basic"
changes (i.e., xpp, xlatexpp) then for some of "us" it's not so cavalier.
(or is it *arrgggghhhh* 3 more weeks of translating?)

Or is it hopeless?  Can I ever get a "next version" that'll Scheran
translate in finite time?

A real encouraging sign...

What does this mean for we (er, I mean I) the users (er, user)?

I've never seen or used "calc", so what... ("he ignores the above")...

Oh shit! (He says to his alter-ego.)  You can't be serious?!?!?!?
At least there aren't "significant" changes to the visible interface???
(i.e., *x.hxx stuff)??
[If this is so, you can't seriously expect your current schedules to
be valid, so I pass on any threats I may make to your person.]

I don't think this affects us.  I hope not, anyway.

Please note my concerns over basic interface changes, if these change,
then the whole focus of my work changes.  (And I had such good things
saved for next week's meeting!)
