User-Agent: T-gnus/6.14.5 (based on Gnus v5.8.7) (revision 03) REMI/1.14.3 (Matsudai) Deisui/1.14.0 (Kikuhime) APEL/10.2 Emacs/20.7 (i386-unknown-openbsd2.7) MULE/4.0 (HANANOEN)

This patch updates _cvs.

* expand cvsroot specified in command line to fix following error.

% cvs -d ~/.cvsroot import cvs <TAB>
[checkout aborted]: CVSROOT ~/.cvsroot must be an absolute pathname
module name

* Subcommand list are now generated from `cvs --help-commands' and
  `cvs --help-synonyms'.

* Remote modules are now completed.

* The second argument of `cvs import' (vendor branch) is completed.

* use _call to call cvs.
