[PATCH 2/2] doc/gitremote-helpers: match object-format option docs to code

[Jeff King <peff@peff.net>]

Git's transport-helper code has always sent "option object-format\n",
and never provided the "true" or "algorithm" arguments. While the
"algorithm" request is something we might need or want to eventually
support, it probably makes sense for now to document the actual
behavior, especially as it has been in place for several years, since
8b85ee4f47 (transport-helper: implement object-format extensions,
2020-05-25).

As I discussed in patch 1, remote-curl does handle the "true" thing
correctly. And that's really the helper that matters in practice (it's
possible some third party helper is looking for the explicit "true", but
presumably they'd have reported their confusion to the list). So we
could probably just start tacking on the "true" in transport-helper.c
and leave that part of the documentation untouched.

I'm less sure of the specific-algorithm thing, just because it seems
like remote-curl would never make use of it anyway (preferring instead
to match whatever algorithm is used by the http remote). But maybe there
are pending interoperability plans that depend on this?

I guess it would not hurt to leave it in place even if transport-helper
never produces it. On the other hand, any helper which advertises the
"object-format" capability is supposed to support it, and without the
transport-helper side being implemented, I don't know how any helper
program can claim that.
