Subject: lesskey: don't color indicator for overlong lines
X-Git-Url: https://ruderich.org/simon/gitweb/?p=config%2Fdotfiles.git;a=commitdiff_plain;h=3e7a01c3a9d7c71a9e4a1981815efe54f7ed282e

lesskey: don't color indicator for overlong lines

Recent versions of less draw an indicator when an overlong line is not
wrapped but cut off. The indicator is nice but the strong color is
annoying.

Also add compatibility to setup.sh for older less versions.
