- %s, %d, %c, %x and %% only (without anything between the % and the s,
- d, &c). Callers who want something fancier can use sprintf.
-
- If ERRNUM is nonzero, print its corresponding system error message.
- Exit with status EXIT_FAILURE if STATUS is nonzero. If MESSAGE is "",

- I think this is largely cleaned up to the point where it does the right
- thing for the server, whether the normal server_active (child process)
- case or the error_use_protocol (parent process) case. The one exception
- is that STATUS nonzero for error_use_protocol probably doesn't work yet;
- in that case still need to use the pending_error machinery in server.c.
-
- error() does not molest errno; some code (e.g. Entries_Open) depends
- on being able to say something like:
- error (0, 0, "foo");
- error (0, errno, "bar");
