[talk-au] Tagging for sports courts that are similar to, but not quite tennis

[Josh Marshall]

I've added these courts in changeset:
https://www.openstreetmap.org/changeset/99342134#map=19/-32.94127/151.76493

They are concrete courts with a large wall on one side so one can
practise solo, or play a bit more like squash if you have a partner. I
know it colloquially as playing 'bat ball', but a search for the term
shows it's not used much.

Is tagging as sport=tennis (as I have done already) appropriate?
