Yes they are and yes I do :)

That is very useful, thanks. And after reading the docs you pointed me 
at, I installed filladapt-mode as well, which makes it even better.

Essentially I want to restrict the width so I can just cut & paste my 
code into emails without the email mangling it.

It does sometimes break the line in surprising places, but that's not an 
issue.

There is only one quibble that I have with the arrangement as I now have 
it, and the cc-mode help, which is great, is not telling me how or why 
it happens:

  - when auto-fill breaks a line, it ignores my idea of what the 
indentation should be. I have to hit tab (or an electric key) for the 
indentation to sort itself out. I assume my settings are in need of some 
adjustment, but I don't know which of the following it is:

(c-set-offset 'topmost-intro-cont c-basic-offset)
(c-set-offset 'inline-open 0)
(c-set-offset 'inclass 4)
(c-set-offset 'substatement-open 0)
(c-set-offset 'block-open '-)
(c-set-offset 'objc-method-intro 'c-lineup-arglist-intro-after-paren)
(setq c-electric-pound-behavior '(alignleft))
(local-set-key [return] 'newline-and-indent)


Thanks again,
Adam
