Subject: screen: moved code to paint_top_window2()
X-Git-Tag: v0.12_alpha1~322
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=001ff5ee87b755c8c5371690222fc3ac16ba0602;p=ncmpc.git

screen: moved code to paint_top_window2()

Nearly all of the code in paint_top_window() is on indent level 2,
just because it depends on a condition.  Make this more readable and
move to indent level 1 by moving this code to a separate function.
