We shouldn't create workarounds for upstream abandoned functions -
that's their decision to blame, agreed (so no env.d/GREP_OPTIONS parsing in
some script).

However, we should keep our improvement base available. In this case -
the alias should be installed. I'm not even sure if there's any
rationale to have it back in commented-out version, but IF there is - we
should drop at least colorls and which - people NEED to set them on
their own, don't they?
