Iterating through all possible completion words undermines the main
reason for __gitcomp_nl()'s existence: to handle potentially large
number of possible completion words faster than the old __gitcomp().
If we really have to iterate in a subshell, then it would perhaps be
better to drop __gitcomp_nl(), go back to using __gitcomp(), and
modify that instead.
After all, anyone could drop a file called git-cmd-${meta} on his
$PATH, and then get cmd- offered, because completion of git commands
still goes through __gitcomp().
