I was hoping someone else would come forward and review this but
that hasn't happened so I'll try to keep this moving as best I can.
I'm happy with the changes for 1, 3 and 4 above but my elisp skills
aren't up to reviewing 2. (It's been 20+ years since I last wrote
anything like elisp when I was hacking together some serious BRIEF
macros but that's another story!)

Can I ask for the following?

1. An Emacs user not using Mew to confirm the above still works for them?

2. A core developer using Emacs (hi Vincent :-) ) to review it?

Otherwise,

bb:approve
