Improve the regex to match Gpm_Type.
  Rename "func" to "fn" to be gentle to awk; This prevents errors like
  awk: cmd. line:7:                func=substr($0, idx);
  awk: cmd. line:7:                ^ syntax error
  awk: cmd. line:8:                gsub(/\n/, " ", func);
  awk: cmd. line:8:                                ^ syntax error
  awk: cmd. line:8: fatal: 0 is invalid as number of arguments for gsub
