Reverting your buffers
======================

`R'
     If you are editing (or just viewing) a file in a buffer, and that
     file is changed by CVS during a `cvs-update', all you have to do
     is type `R' in the *cvs* buffer to read in the new versions of the
     files.

     All files that are `Updated', `Merged' or in `Conflict' are
     reverted from the disk.  Any other files are ignored.  Only files
     that you were already editing are read.

     An error is signaled if you have modified the buffer since it was
     last changed. (`cvs-mode-revert-updated-buffers').
