i am reporting a bug in emacs.
this is not a bug in the conventional sense, but one i consider
egregious enough to want to do something about.
thus...
the bug is essentially in the documentation...
i want to set the default comment-column to 10 for all my C source code
files. (i.e. files w/ .c extensions.)
i have been through the manual several times and i've tried many
permutations and combinations of emacsian or lispian things to
try to get the value be set to other than 32 automatically.
and nothing works and i can't seem to find out how to set the value
by any means other than by using M-x set-variable .. comment-column ..
10 from the minibuffer EACH TIME I GO TO A NEW LOCAL BUFFER!!!
i don't like this!!!! i wish to set my own defaults in an effortless
way, say in my .emacs file, and i want the documentation to provide
clear explanations of how to do this so that i don't have to spend
30 futile minutes trying things in hopes that i'll trip over what
works...
so how do i do it?
by the way, my version is: 18.52.1 of mon 9 1989 on _venus (vax-vms)

        thank you very much
