Hi Martin,

actually you have detected a small bug.  The two flag bytes 224=0xe0 and
232=0xe8 differ by the first pixel being white or black respectively.  This
is, however, for a character with W=H=0 and no pixels at all.

The color of the first pixel is taken from count[0], not initialized in this
case but usually inherited from the previous character.  Since this is the
first character the count array has just been acquired by malloc() with
unspecified contents.

Should now (r27153) be fixed.
