bug in eputil.c

If you make the mistake of setting EMBPERL_OUTPUT_MODE=XML
instead of EMBPERL_OUTPUT_MODE=1
then embperl_OptionListSearch in eputil.c will go into
an infinite loop.

I don't see how that code can possibly work, since
both sKeyword loop and the pEntry->sOption inner loop
look like infinite loop risks to me.

That's true. This part of the code is not really finished and therfore
not documented. So don't use it.

Patches are of course welcome

Well, I didn't use it deliberately. I just misread
http://www.ecos.de/embperl/pod/doc/Config.-page-2-.htm#sect_44
and thought I could set output mode to "XML".
