The lorem executable has 2 issues:
* The elements of the array need to be separated by " " or "\n".
* A final "\n" needs to be output (to get a POSIX text file and
  to avoid issues in an interactive shell).

Without the separators, the lorem executable is useless.
For instance, with bash:

vinc17@qaa:~$ lorem -w 5
accusantiumeosrationeestofficiavinc17@qaa:~$

One cannot see the separation between the words and this is mixed up
with the shell prompt.

I've attached the patch I've written for the pull request upstream.
