I've had moderate success using the 'a' and 'w' options to
'formatoptions'. See
:help auto-format
:help fo-table
In addition to the warnings in the reference manual, be aware that
there is a bug in the 'a' option in recent versions of Vim that
affects the automatic formatting of _indented_ paragraphs. The bug
was introduced by a fairly recent change, though, and I think it
will be resolved before long.
By "moderate success", I mean that it works well enough that I use
it while writing e-mail, but it seldom formatted the way I wanted it
to when I tried it in other circumstances, so I format everything
else with "gqap", etc.
