Bug#138161: xdvi SIGUSR1 fix

[Angus Lees <gus@switchonline.com.au>]

Tags: patch

changing the end of the xdvi script to exec xdvi.bin, rather than
just run it is a simple (and more efficient) fix.

the xdvi script always returns 1 or 0, whereas this version will
potentially return other non-zero codes on error.

i note that the oxdvi wrapper does similar, and the "exec" code seems
to have been commented out of the xdvi script (presumably when the
.dvi.gz handling was added).

i noticed this while trying to use whizzytex with xdvi. matthias will
be happy to know whizzytex/xdvi works with this fix.
