Sorry to bother both Emacs lists with this, but it can't be
as hard a problem as it seems to ...  All I'm trying to do
is produce a C program that can be run through vgrind with
reasonable-looking output.  Unfortunately, my experiments
with 'tabify' and 'edit-tab-stops' and the like have been
total disasters so far, and I have had zero luck making
things line up for vgrind.

I am sure it is because of my total lack of understanding
of tabs in Emacs, because things like the following continue
to puzzle me:

	I create a program file, with tab stops every 4 spaces.
    (Verified by 'describe-variable tab-stop-list'.)  There
    really seem to be tabs, since the cursor jumps on C-f.

    I save the file and grep for tabs; sure enough, there
    they are.

    I 'untabify' the entire program, and the tabs seem to go
    away (cursor moves smoothly).

    I save the file again, grep for tabs, and -- oops, still
    got tabs!

A second "experiment":

    I set tabs every 4 spaces over to column 40, and none
    after that.  I 'tabify' the region, and -- again oops,
    there are still tabs being used past column 40.

In my weak little voice, I cry "Help?".

Seriously, thanx muchly to anybody who can point me to the
right documentation, mode, oracle, ...  And by the way, I
am using GNU Emacs 18.44 on a diskless Sun 3/50.  Thanx!
