I'm doing this. I believe these mail issues, as they interact with
mailing lists, are a Hard Problem. I'm not sure how much progress has
been made on this by the admins, but they certainly haven't been
disregarding the problem.

I'm not saying your description in terms of CC Mode internals was
incorrect, but I'd like to provide an implementation-independent
description that can be easily verified. (Also, in case it hasn't
been posted recently, the Emacs Wiki discusses this idea in some depth
Thanks, I've read that. I've also downloaded the pertinent Elisp file.
I'm not quite sure how smart-tabs-mode works, yet, so I'm also not sure
what a secific CC Mode implementation could add.
The definition of "continuation" is simply that tabs are used whenever
the user chooses the width of indentation and spaces are used whenever
the editor chooses it (by comparing column positions in the text).
So, roughly speaking, if a CC Mode "offset" is + or ++, then tabs would
be appropriate, otherwise spaces.
There is a tacit assumption here that the amounts of indentation
chosen by the user are expressed in units of tabs. Conveniently, CC
Mode already defines indentation in terms of levels, so this just
means that a level equals a tab--i.e., that c-basic-offset and
tab-width are not independent. It probably makes sense to, when this
style is engaged, (setq tab-width c-basic-offset) after computing the
latter from whatever other style information since it is more specific
than any global setting of tab-width.
Yes. I'll work out the precise details.
But I'm now wondering why I should want to write a CC Mode specific
Hope this helps,
Very much so, thanks!
