Some video= options might have a value that contains a dash. However, the command line parsing mode considers all dashes as the separator between the mode and the bpp count. Let's rework the parsing code a bit to only consider a dash as the bpp separator if it before a comma, the options separator. A follow-up patch will add a unit-test for this once such an option is introduced.
