Subject: minor cleanup regarding forward scrolling usage, also only scroll one line
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=42f661410d8a513800dc49721bd8c0ac164cb502;p=openbsd

minor cleanup regarding forward scrolling usage, also only scroll one line
at a time rather than 10.  (slower, but not so distractingly ugly anymore)
