Bug#452003: x11vnc: Option -noxinerama not recognized

> 19/11/2007 10:20:52 *** unrecognized option(s) ***

This has been fixed today in the upstream x11vnc dev. tarball and will
be released in 0.9.4 (next 1-3 months I think).

In private email with the bug submitter, we see that the "multiple desktop"
observation was due to confusion about the -ncache mode.  That effect has
nothing to do with x11vnc's xinerama mode.

The above Xinerama printout is unfortunate and confusing in that it
seems to appears in a non-xinerama/multi-head setup.  Evidently the
X server is configured to activate Xinerama even when there is just 1
graphics card/output?

I will try to improve this. I need to test on some newer distributions
to see what is happening..

BTW, x11vnc's Xinerama mode is really esoteric: it only does something
if the screen is not rectangular (e.g. 1280x1024 monitor next to 1024x768
