Re: [PATCH 2/3] tests: test terminal output to both stdout and stderr

Jeff King wrote:

Some outputs (like the pager) care whether stdout is a

This patch sets up both. Technically speaking, we could go
further and set up just one (because either the other goes
to a terminal, or because our tests are only interested in
one).

This makes test_terminal more realistic, too: the usual case is for
stdout and stderr to go to a terminal (unless explicitly captured or
redirected).

Tests can use 'test_terminal sh -c "foo >/dev/null"' to test that a
command correctly handles being run with stderr a terminal and
stdout not.

And I doubt this would make test_terminal much slower.

So for what it's worth:

Thanks.
