I have; the recursion is endless.  If you really MUST stay in vi (not
fork a subshell) to format your paragraph, one ugly solution to the
problem is:

map ^XF jf k0J72^V|EB^Hr^V^M
map F {j^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF^XF

Or put as many control-X F's in your format-paragraph macro as you
want.  I usually don't format paragraphs longer than 20 lines, though. 
This solution is much faster than forking a sub-shell, but an ugly hack.

I looked for that weird turing-machine in vi macro language, but
couldn't find it.  Was it archived anywhere?  Did Brandon post it in
.sources.misc?  Anyone want to re-post it or send it to me?

Cheers y'all,  -Mitch
