Yeah. Either way is fine by me, since the projects I work on already
have TAGS in their .gitignore.

Does anyone really configure their system this way? XDG warns about
relying on the cache, but in practice I think that is a warning for
developers -- the model being that the user should be able to delete the
cache at any time. At least on the systems I've used, the cache is
persistent in practice.

It should certainly be an option. Memory is just no barrier on typical
machines these days.

Please try it on a non-trivial project before committing to something.
IME a lot of these things work fine for simple projects, but when I want
to use them on gdb or gcc, they are unusably slow.
Anyway, thanks for working on this. Lack of incremental update is why I
stopped using etags, in favor of ggtags. I hope someday to switch back,
since etags has some features that GNU Global lacks.
