There was no need for this once __git_reassemble_comp_words_by_ref() was
introduced. Now irrespective of the value of COMP_WORDBREAKS, words are
always joined together.

By default COMP_WORDBREAKS does contain a colon, and if it doesn't
somebody probably has a reason for it.

Completions are not supposed to modify COMP_WORDBREAKS and none of the
completions in the bash-completion project do.

We manually set it in Zsh so the Bash script is not confused.
