* pcvs.el: Add a minimal leading commentary.
(cvs-make-cvs-buffer): Change the header part by removing the startup message and adding a `Module' entry. Also replace the FOOTER and HEADER special fileinfos with the new support in ewoc for updating its own footer and header. (cvs-update-header): Update to use the header/footer of the ewoc. (cvs-mode): Use define-derived-mode and set truncate-lines to t. (cvs-is-within-p): New function. (cvs-mode-run): Take advantage of `save-some-buffers's new ability to only examine some subset of the buffers. * pcvs-info.el (cvs-fileinfo-pp): Use the new property-preserving `format' instead of our own ad-hoc functions. Remove HEADER and FOOTER cases, now handled in the EWOC. (cvs-fileinfo<): Remove HEADER and FOOTER cases. * pcvs-parse.el (cvs-parse-run-table): Change message for unknown output to avoid scaring the user.

(ewoc--refresh-node): Don't take the whole EWOC but only the relevant PP part of it and also make it work for footers and headers. (ewoc-create): Drop POS and BUFFER arguments. Use the DLL's dummy node to store the end-of-footer position. (ewoc-map, ewoc-invalidate): Update call to ewoc--refresh-node. (ewoc-refresh): Remove unused `header' variable.
