PATCH: _cvs update.

[Tanaka Akira <akr@xxxxxxxxxxx>]

This is _cvs update.

* more cvsignores for _cvsaddp.
* _cvsaddp tries completion without cvsignores if there is no
  completion candidates.
* cvs_roots is renamed to _cvs_roots and the definition is moved to
  toplevel.  Also, its definition is now external command free.
* some code beautification.
