Re: pending-undo-list is not buffer local

Not by default.  If you want to write a function which say, tries to
undo changes simultaneously in two or more buffers in some lock-step
fashion, you can always make it local yourself (and probably
`undo-in-region' as well).

I think this wouldn't make much sense since `buffer-undo-list' isn't
permanently buffer-local either.
