[dm-devel] tiny bug

[Benjamin Marzinski <bmarzins redhat com>]

mulitpathd was crashing when I entered an empty line at the CLI prompt, because
the output buffer from get_word was being checked to see if it was NULL, but
get_word never explicitly sets the buffer to NULL if there is no word.

The patch fixes this.
