Subject: [PATCH] term_init(): initialise term->ldisc.

In live uses of Terminal, we always give it an ldisc almost
immediately after creating it. But the new test_terminal program
doesn't, which allows it to be an uninitialised pointer. Apparently I
got lucky while testing this the first few times.
