From: Geert Uytterhoeven <geert@linux-m68k.org>
It is fairly common for named video modes to contain dashes (e.g. "tt-mid" on Atari, "dblntsc-ff" on Amiga). Currently such mode names are not recognized, as the dash is considered to be a separator between mode name and bpp.
Fix this by skipping any dashes that are not followed immediately by a digit when looking for the separator.
