[21.3] pcl-cvs.el suggestion: make *cvs* buffer headers shorter

[Jari Aalto+mail.linux]

In GNU Emacs 21.3.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2004-08-03 on raven, modified by Debian

The layout of *cvs* buffer looks like this:

  PCL-CVS release v2_9_9

  Repository       : foo@some.site.com:/version/control/public/projects
  Working directory: 
/home/staff-f/foo/operating-systems/project/this.site.com/etc/spamassassin

I'd wish that the headers were shortened so that valuable space were left for
the actual values. The defaults could simply be:

  Repository: foo@some.site.com:/version/control/public/projects
  Directory : 
/home/staff-f/foo/operating-systems/project/this.site.com/etc/spamassassin

It would be good if the header names were user configurable and stored
to variables, so that they could be shortened even more, like this:

  Rep: foo@some.site.com:/version/control/public/projects
  Dir: 
/home/staff-f/foo/operating-systems/project/this.site.com/etc/spamassassin
