Okay, would we prompt for an existing, bespoke TAGS file, or for a 
project directory to auto-generate tags from?

The latter case means we'd basically mark that project as the "default" 
for the purposes of etags-regen until the end of the current session.

It wouldn't include tags from any of the project-less files, though. But 
if you were only thinking about non-file-visiting buffers, that's not a 
problem.

All right, see above.
