Subject: [PATCH v17 1/8] tab completion for reindex(verbose)..

..which was added at ecd222e77 for v9.5.

This handles "verbose" itself as well as the following word.

Separate commit as this could be backpatched to v12 (but backpatching further
is less trivial, due to improvements added at 121213d9d).
