It works then because "HEREDOC" is equal to "HEREDOC", when the space at 
the end is present it's "HEREDOC ".  I just tried it at the command line 
using bash and when there was a space at the end it did not blow up, it 
merely included the "HEREDOC " as the last line.  Removing the space 
caused it to work correctly.  I did not try it under perl or php.
