This patch changes the code so can support more than one type
delimiter
on the command line. Now you can use "||" as well as "--". " || "
works
better with SLOF currently available. There is a bug in some cases
using
SLOF where "--" is not treated as desired.
Patch has been tested and ready to go.

The -1 is because sizeof() includes '\0', so you can drop it here.
