A typical case is that the file is somehow modified after the CVS
process starts, so the application of the patch fails.  Another is
that the file contains binary data, but is not marked as -kb, and
patch gets confused.

When I wrote the code originally, CVS would invoke patch as a separate
program.  That could fail in various ways, so I added the second loop
as a fallback so that cvs update would work correctly even if patch
failed.
