more refinement of IM patch to fix Windows pathnames with spaces

server-tools/instance-manager/instance_options.cc:
  move declaration of end to start of function so gcc is happy
server-tools/instance-manager/parse_output.cc:
  remove space before =
  use my_isspace to determine if *end is white space
  remove comments related to get_word which was removed
  replace tab character with appropriate # of spaces
