Fix __reassemble_comp_words_by_ref()

If a word is made up of multiple word separator characters:

   $ a b::<TAB>  # CWORDS are: a, b, and :: (correct)

__reassemble_comp_words_by_ref() couldn't handle this.  It assumed CWORDS were:

   $ a b::<TAB>  # CWORDS: a, b, : and : (but they're not)

Added test case for this.  To run the automated tests:

   ./runUnit _get_cword.exp
