[PATCH] make cmdline options permanent

I noticed this behavior in scsi_id and it was listed in the TODO as:

- Document that config file options override command line options, or fix
  the code. This means a '-b' in the config file disables any -g on the
  command line.

I chose to fix the code. Though, it appears to be a non-elegant solution to 
me, it seemed the least intrusive into the existing code.
