The above is only true for the project whose TAGS was manually
visited, right?  IOW, it's not that once the use invokes
visit-tags-table once, this mode will be effectively disabled for the
entire session, right?

If so, I suggest to make it clear:

  If you select a tags table manually (for example, using
  \\[visit-tags-table]), then this mode will be effectively disabled
  for the project or the directory tree from which the tags table was
  visited (the mode will still auto-regenerate tags tables for other
  projects and directory trees).  Use \\[tags-reset-tags-tables] to
  countermand the effect of a previous \\[visit-tags-table].

Otherwise, this LGTM, thanks.
