[Qemu-devel] [PATCH] fix ncurses output

[Bernhard Kauer]

The ncurses console uses mvwaddchnstr() to print a line of output
to a ncurses pad. Unfortunately this routine stops to print further
chars if a zero-char is seen in the line. This has the effect that
parts of a line are never redraw.

The following patch puts spaces instead of the zeros into the line-buffer.
Please note that this change affects other consoles as well and is
perhaps undesirable. Comments?
