BDECFLAGS cleanup

Fix warn format

Back out all drainwait changes. It is enough controllable via sysctl or
comcontrol, having it in stty cause too many problems with existing drivers
and tty access permissings of non-superuser.

gfmt: set 'changed' flags only if something really changed.

Add ability to manipulate with drain wait time

$Id$ -> $FreeBSD$

Correct use of .Nm. Add rcsid.

Typo in usage string. Looks like the man page now.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

-Wall cleaning.

Improve the recently changed and an old error message: don't report probe
errors.

stty fails with a non-obvious error message if it's run on a non-tty
stream, such as a rsh or vi pipeline.

The error message is:
stty: TIOCGETD: Operation not supported

It's immediately obvious to the knowledgable hacker type, but not
exactly comforting to the user who's not native to unix. It's
especially confusing if there's a stty command in their .cshrc and
it's showing up on rsh output.

(Fixes PR #bin/573)

Remove trailing whitespace.

Fix `stty' on the output of `stty -g'. The changes for the gfmt1 option
weren't TIOCSETD'd unless another option changed something.
