Subject: Remove useless variable "height" in function traverse().  It is
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5ec43f377baec23910ddca3503b3d9727a415a00;p=openbsd

Remove useless variable "height" in function traverse().  It is
assigned the value of "top" but never changed so just use top instead.
