No, that is different.  The options that occur after `diff' can be set
in ~/.cvsrc.  It's OK for your cvsdiff script to just use the values
from the user's ~/.cvsrc.

But the options that occur before `diff' can't be set in ~/.cvsrc,
except by setting them globally for all commands, and you can't set
`-n' for all commands, otherwise `cvs commit' won't work.

`cvs -n diff' avoids taking a CVS lock in each directory before doing the diff.
This speeds things up, and avoids long "waiting for lock" delays.
