[texworks] Trouble with auto-pst-pdf

--option and -option are synonyms in web2c-based programs, always have
been, always will be.  This is in the "Option conventions" node of the
web2c manual.  (Aside: I wish Olaf had not changed the help msgs et
al. to favor -option, but now I figure changing everything back will

I believe it is enabled by default in TeXShop.  It is not enabled by
default in TeX Live.  I think it is far too dangerous, even though it is
so useful.
