6.0.3 added -g and -r options to the mod command, but they can't be used
together. This patch allows "-r -g" or "-rg" or "-Srg" etc.
crash-6.0.3> mod -r -g -S /usr/lib/debug/lib/modules/3.1.4-clim-3-amd64
mod: invalid option -- 'g'
Usage:
mod -s module [objfile] | -d module | -S [directory] | -D | -r | -R | -o | -g
Enter "help mod" for details.
Still working on the flaky module symbol problem...
