If that is the case, isn't it incorrect to offer "tags-tree" as one of
the org-agenda custom commands?  Since it can't be safely invoked as
part of org-agenda?

One suggested possible solution:  Change tags-tree argument to (tags
tree <filename>), then do some kind of with-excursion to get into the
buffer for <filename> (in org mode).  But here we're running up against
my limited understanding of the tags tree.  Is tags-tree even really an
agenda command?  I.e., does it build a new agenda buffer that we can
use, or is it a way of viewing the current buffer?  I think the latter.
 If that is correct, it suggests ....

Alternate solution:  remove tags-tree from the set of org-agenda
commands.  tags-tree isn't really an agenda-building command, and should
not be treated as one.

Note also that this means that this doesn't work as a solution to my
problem, because it requires all of the car category items to appear in
a single org file, and ignores the org-agenda-files setting.  So, for
example, I can't have work-related in-car tasks in one org file and
personal chores that are in-car tasks in another.  :-(
