I was thinking about setting TAB in `overriding-terminal-local-map'...
(I've never used that map myself, though, so I may be misunderstanding
how that variable works.)

Yeah, it is pretty logical addition.  The main problem with doing
something like this is that there's a bunch of other similar variables,
like c-tab-always-indent/snmp-tab-always-indent/opascal-tab-always-indents
(and seemingly an infinite number for some reason), and for consistency,
we'd have to allow `never' for all of these (and change all the usage
sites).

I'm not sure that's worth it if there is a simple way of binding TAB.
We could just mention that in the doc string of `tab-always-indent'.
