thanks

Here is a patch to fix this problem.  It teaches the script to ignore
empty lines, and to write an error if the line don't have at least two
words.

This is the output when I tested it

  Generating locales...
  error: Bad entry 'en_US.ISO-8859-1 '
  error: Bad entry 'en_US.UTF-8 '
  Generation complete.
