Commit Message

xargs exits on empty line from stdin

* BSD versions of xargs don't support the -l option
* Standards document for xargs mentions -L but not -l [1]
* Follow GNU version and accept -l as an alias for -L, but list standard -L in usage string
* Behaviour of -L/-l didn't match xargs on my linux system: input loop was terminated on
  first empty line of STDIN
* Skipping empty lines makes the behaviour match GNU version
