nohup args: where's user friendliness?

[Dan Jacobson]

$ nohup -xx
nohup: appending output to `nohup.out'

excuse me, how did you know I had an nohup.out?  If you aren't going
to check then say "creating or appending output to `nohup.out'"

$ cat nohup.out 
/usr/bin/nice: -xx: No such file or directory

well, shouldn't nohup be more picky in catching args?
>   The only options are `--help' and `--version'.  *Note Common
well, ok, but...
$ nohup --vv
nohup: appending output to `nohup.out'
picky picky, where's user friendliness? I mean it's like guessing
passwds to get a little help around here. -? -h etc all bombs.  How
about making case -*) call $usage, and -- allow the rest of the args.

$ nohup --version
nohup (GNU sh-utils) 2.0.11
