Subject: env: only use color diffs on terminals
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e495a050693952956a81847669b8b7888b4cd769;p=openwrt%2Fstaging%2Fblocktrron.git

env: only use color diffs on terminals

When sending script/env diff's output to a file or pipeline, you
don't want escape characters for ANSI color sequences fouling the
byte stream.
