If we didn't get a message from command line, and there is no
previous tag object to read the message from, there is nowhere but
editor to grab the message to be used, so !use_editor would trigger
an error if force_editor (i.e. the command line explicitly said
either --edit or --no-edit). Makes sense, but I needed to cheat and
look at cmd_tag() to see how "force" is set to understand what is
going on. I have to say "force" is not a good name for this field;
is this use similar to what we typically use an additional _given
field?

If there is no --[no-]edit and there is no preexisting message, we
need to use the editor. If the command line explicitly said --edit,
we also would use the editor. OK.
But it starts to make me wonder if you rather want to replace the
single bit use_editor field with an enum with three possible values
(enum { EDITOR_UNSPECIFIED, EDITOR_YES, EDITOR_NO } use_editor).

Are we certain at this point in if/else cascade that prev is a valid
tag? How?

This NULL tells us something about what I mentioned in my review on 1/3.

Why do these two need explicit --edit option to invoke the editor?
That smells like an unnecessary backward incompatible change.
Thanks.
