From 8aa81ea8c418df3f6f57f57aa5fe8c45399394c6 Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Sat, 4 Apr 1998 05:21:44 +0000 Subject: [PATCH] (vc-parse-cvs-status): New function. (vc-fetch-master-properties): Moved cvs status retrieval to the above. (vc-backend): If a file is not registered, remember that by setting the property to `none'. (vc-name): Use the mechanism of vc-backend to compute the value. (vc-after-save): Don't access vc-backend property directly. --- lisp/vc-hooks.el | 101 ++++++++++++++++++++++++++--------------------- 1 file changed, 55 insertions(+), 46 deletions(-) diff --git a/lisp/vc-hooks.el b/lisp/vc-hooks.el index 418bdfe6e76..6fe4b75c7c8 100644 --- a/lisp/vc-hooks.el +++ b/lisp/vc-hooks.el @@ -5,7 +5,7 @@ ;; Author: Eric S.
