Package: grep Version: 2.14-1 Severity: normal Dear Maintainer,
When grep is asked to colorise matches (e.g. grep --color=tty), it outputs an sgr sequence to switch to (e.g.) red text colour, followed by a clear to end of screen. (apparently, this is the patch that implements that: http://git.savannah.gnu.org/cgit/grep.git/commit/src/grep.c?id=1eb74b3a38f16192097fc1d51a9b219165c540aa) The problem is that this corrupts the character before the match when the match happens to be at the end of the line. e.g. when grep prints "1234\e[1m\e[Kuuuu", in a terminal that has 4 columns, it expects the first line to be 1234, and the second be a coloured uuuu: 1234 uuuu However, the result in xterm is: 123u uuu While the result in urxvt is: 123 uuuu i.e. in xterm a character is missing, in urxvt it gets cleared. this is because the cursor is at the end of the line for the last character of the line, so a clear to end of screen erases that character. (apparently xterm and urxvt disagree on whether to clear the cursor-past-margin flag, but they do agree that clearing to end of screen clears from the visible cursor position onward). -- System Information: Debian Release: 7.1 APT prefers stable APT policy: (990, 'stable'), (500, 'unstable'), (500, 'testing'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.10-3-amd64 (SMP w/12 CPU cores) Locale: LANG=C, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages grep depends on: ii dpkg 1.16.10 ii install-info 4.13a.dfsg.1-10 ii libc6 2.17-93 grep recommends no packages.
