This allows turning off specific colors for o+w dirs for example. * tests/ls/color-dtype-dir: Add a case to test that turning off coloring for o+w directories, falls back to standard dir color. * NEWS: Mention the fix Introduced by commit ac467814, 2005-09-05, "Colorize set-user-ID ... files and sticky ... directories." --- NEWS | 3 +++ src/ls.c | 24 +++++++++++++----------- tests/ls/color-dtype-dir | 20 ++++++++++++++++++++ 3 files changed, 36 insertions(+), 11 deletions(-) diff --git a/NEWS b/NEWS index 0f44816..6ef2dea 100644 --- a/NEWS +++ b/NEWS @@ -12,6 +12,9 @@ GNU coreutils NEWS -*- outline -*- to accommodate leap seconds.
