Description of problem:
As shipped with Red Hat 9, vim no longer automatically sets cindent when editing
C code.  This is different (and less desireable) from vim as shipped with all
previous versions of Red Hat, at least as far back as Red Hat 7.1, and I believe
much earlier.  I am in shock that this has not been reported earlier...  I'd
have expected people to have noticed, and to complain.

Note that if you are not seeing this, it is almost certainly because you have
something in your .vimrc which is enabling cindent (or one of the other
auto-indent features).  Rename your .vimrc and any .vim directory, and you
should see the problem.  Except, well, you shouldn't.

I identified where the problem is by perusing a recursive diff of
/usr/share/vim/vim61 on each of a Red Hat 8 and Red Hat 9 system. Doing so
reveals the following code which is present in RH8, but missing from RH9, which
when applied with patch -p1 fixes the problem:
