Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

This commit was generated by cvs2svn to compensate for changes in r11891,
which included commits to RCS files with non-trunk default branches.

Import rcs-5.7, required for full support of cvs-1.6.

This is going to be pretty messy.... Although the vendor import was correct,
both the vendor and release tags are the same "gnu"... :-/
Getting cvs to choose the correct one might be rather interesting...
