FWIW (so please don't claim I'm "insisting" or arguing) -

Like I said:

   That's exactly how I discovered this.

I didn't do it by accident.  Someone can easily do
both tags searching and tags query-replacing, moving
from one to the other.

Clearest (at least for menu purposes) would for there
to be two separate continue commands - continue last
search and continue last query-replace.
