The point of the question was in fact to ascertain what the=20
original purpose of the option was, and how it is to be used.

I was asking because an emacs package was using it, which resulted=20
in unwanted behaviour (see=20
https://github.com/Ergus/gtags-mode/pull/8).

You've been clear that this option is not to be used with=20
GTAGSLIBPATH, which is enough.

This is the simplest solution. There is no possibility now that=20
users could possibly misinterpret the output path now.
