Subject: Improve title updating and remove flickering
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c19f8017cc2dd8753f92f9952e65cfad28acbbe0;p=tig.git

Improve title updating and remove flickering

 - Show line info even if no lines has been loaded, so less has to be
   redrawn.

 - Don't make the view window one line bigger causing the title window
   to be overwritten. This reinstates the bug in last line drawing.
