jlam 4d60064932 Reorder the loop so that we can never get into an infinite loop. We
now pass every line we don't need to process directly through to
msgfmt.  This fixes building pt_BR.po in libgnomedb where all of the
lines end with "^M" and this script wasn't properly detecting a blank
line as a result.
