-draw path ML misses lines

[snibgo]

The following correctly draws three lines that don't have overlapping ends:

Code: Select all

%IM%convert -size 200x100 xc: -stroke #000 -fill None ^
  -draw "path 'M0,0 L99,0  M99,1 L0,98  M0,99 L199,99'" ^

But when I adjust the coordinates of the middle line, so the first and second end where the next line starts, it draws only one line:

Code: Select all

%IM%convert -size 200x100 xc: -stroke #000 -fill None ^
  -draw "path 'M0,0 L99,0  M99,0 L0,99  M0,99 L199,99'" ^

A workaround is to draw the lines in a different order:

Code: Select all

%IM%convert -size 200x100 xc: -stroke #000 -fill None ^
  -draw "path 'M99,0 L0,99  M0,0 L99,0  M0,99 L199,99'" ^

This seems to be a generic problem: when one line ends where the next starts, the second line is not drawn.

Tested with v6.9.0-0 under Windows 8.1.

I can confirm the same results on Mac OSX Snow Leopard and IM 6.9.0.5 Q16
