That part I know. The question was what would a typical value of
that parameter look like in the context of somebody mistakenly
visiting Git smart HTTP endpoint via their browser.
I am basically wondering if it is helping the user enough, or if it
is sufficient to give just the "err" and "hint", and nothing else.

Heh, I wasn't either. The review of this topic was the first time I
seriously read any part of that file, and I think I still only read
just about 20% of it ;-)
Also, will the real Git clients, which are the primary intended
audiences this program is trying to talk to, be OK if we suddenly
start giving a non-empty 404 page?
If any implementations of Git HTTP client this program is serving
(1) uses a 404 response as a cue to decide its next request
(e.g. there may be some "try this URL and if it fails, do another
one" fallback logic), and (2) depends on our 404 response to be
without any body, we'd be breaking the service for our primary
audience, only to mollify those who visit our HTTP endpoint that
they should not be visiting in the first place via the browser,
which would be worse than embarrassing.
Thanks.
