in .options files, change syntax to allow settings on different lines. Syntax rules now are:

any line starting with - specifies options
any other line is a comment
anything from a # in a line to the end of the line is a comment

(Bad) Example:

-bsp -samplesize 16 # do not use default options
-light + -fast # this looks good too, default options are still used
-vis +
-minimap +
