Interesting. I don't know why it does that, but I did discover
this, using Vim 7.3.189 on a Linux system.
$ vim -N -u NONE
:set nu
:set fo+=r
Add "/*" then press and hold Enter. I stopped at 300 lines. All
lines after the first contained the desired " *". Restart vim.
$ vim -N -u NONE
:set nu
:set fo+=r
:let &rtp = $VIMRUNTIME
:filetype indent on
:set ft=c
:scriptnames
1: $VIMRUNTIME/filetype.vim
2: $VIMRUNTIME/indent.vim
3: $VIMRUNTIME/indent/c.vim
Again add "/*" and press and hold Enter. This time the comment
leader changes from " *" to "*" at line 72.
The culprit appears to be $VIMRUNTIME/indent/c.vim, but it contains
only
setlocal cindent
So,...
$ vim -N -u NONE
:set nu
:set fo+=r
:set cindent
Again add long comment block. Sure enough, after 71 lines the
comment leader changes from " *" to "*".
So, Vim formats C comments whether or not 'cindent' is set, but it
does so incorrectly if 'cindent' is set.

Gary
