PATCH: Fix more cases in gas/app.c where UNGET could try to put back an EOF

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a few more cases in gas/app.c
  where it is theoretically possible for the UNGET macro to be called
  when the character being put back is the EOF marker.

Cheers
  Nick
