Use tsetdirt in tscrollup and tscrolldown.
tscrollup and tscrolldown do not use tsetdirt, but their code is equivalent to tsetdirt(orig, term.bot-n); tsetdirt(orig+n, term.bot); tclearregion also marks cleared lines as dirty. In tscrolldown it sets lines from term.bot-n+1 to term.bot dirty, and in tscrollup it sets lines from orig to orig+n-1 dirty. In both functions all lines from orig to term.bot are effectively set dirty, but in tscrolldown lines from orig+n to term.bot are set dirty twice, and in tscrollup lines from orig to term.bot-n are set dirty twice. These patches make it clear which lines are set dirty and sets them dirty once in each funciton.
