cvs status and up-to-date files

[Juha Takala]

Hi!

This information is for cvs version 1.11, on Redhat Linux 6.2 (but I suppose
it applies to other versions, too).

Problem: The output of `cvs status' includes information about all the files
in current directory.  In larger projects there may be lot of files that are
"Up-to-date".  In my opinion, the information (noise?) about them makes the
output less readable.

Solution: I implemented `cvs status -u', meaning "Don't display Up-to-date
files".  The default behaviour is same as before.  The patch is below.

Because I don't know the internal workings of cvs client/server system, I
strongly suggest that someone look carefully if the change is compatible
with the design principle etc.  Feel free to do whatever you like.
