Two basic awk things to think of in this kind of situation:
  1. If the default FS is used, test $1 instead of $0. That way you are not dependent on leading spaces that may or may not be there.
  2. If you must use getline, use it conditionally while testing if the return code is >0. For example: if((getline a)>0)
