From 1051b3b3ef16e4ff1575ef22eec533a80fc7142d Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Fri, 20 May 1994 23:14:58 +0000 Subject: [PATCH] (Finsert_file_contents): Declare buffer as unsigned char. When comparing with file size convert same_at_start to distance to buffer start. If the file matches the buffer contents truncate the buffer to the size of the file. --- src/fileio.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/fileio.c b/src/fileio.c index 60473ede63d..8d02ca3fdaa 100644 --- a/src/fileio.c +++ b/src/fileio.c @@ -2694,10 +2694,12 @@ and (2) it puts less data in the undo list.") immediate_quit = 0; /* If the file matches the buffer completely, there's no need to replace anything. */ - if (same_at_start == st.st_size) + if (same_at_start - BEGV == st.st_size) { close (fd); specpdl_ptr--; + /* Truncate the buffer to the size of the file. */ + del_range_1 (same_at_start, same_at_end, 0); goto handled; } immediate_quit = 1; -- 2.39.5
