#239 edge-1.35 ignores bad command-line options

I invoked edge.macosx with the following command-line:

edge.macosx -unknownoption -whoami -iwad wads/doom2.wad

and edge never complained about the bad options. I found this by
actually trying to use -opengl and it never said anything about it,
either, nor did I notice any change in how edge ran. I was trying to
confirm that OpenGL ran on my Mac OS X 10.6.8 system. I noticed
that -opengl was not an option listed in the README.txt file, so that
led me to try the garbage options above.

This is your edge.log file when edge ran.
