I don't trust myself (at least on anything important) with either
the "write as you go |w suffix" option or the 'autowriteall'
(that option makes me shudder a little), so I usually use the
'hidden' option, allowing me to go back and see what I
modified^Wscrewed up before I commit the changes to disk.

Fortunately, restoring is usually as simple as either

:bufdo e!

or

:bufdo u

depending on the state of things.
