Ahh. You have indeed discovered a real bug, still broken in the latest git sources. $ rm -Rf a b $ ln -s a b $ LS_COLORS=ln=target src/ls -ld --color=auto b lrwxrwxrwx 1 eblake None 1 2010-01-01 06:41 argetmb -> a > There must be some good reason why 'ln' accepts to create such links in > the first place.

The m is leftovers from the fact that \033[t is a valid terminal sequence, when normally you would use \033[34m as the terminal sequence to select blue.
