[Qemu-devel] [PATCH v2 4/6] qemu-options.hx: mention retrace= VGA option

[Matthew Ogilvie <mmogilvi_qemu@miniinfo.net>]

The feature was added in commit cb5a7aa8c32141bb Sep 2008.
My description is based on "Better VGA retrace emulation (needed
for some DOS games/demos)" from
http://www.boblycat.org/~malc/code/patches/qemu/index.html

This is the first version of this patch.  I noticed this was missing
when I wanted to add documentation for my own VGA option in the next
patch...
