I'm not sure if this is really a problem. Pd 0.45 supports setting a box
width (for objects, messages, comments) that is saved with the patch.
Those patches still can be opened and read by previous versions of Pd.
This is done by storing the box width after a comma on the object
creation line:

#X obj 135 129 osc~ 3000, f 25;

Similarly, this could be done for connections:

#X connect 0 0 1 0, add some connection props here;

Of course, this information is lost when saving the patch with a Pd that
doesn't understand the format extension. Also, the extension might cause
an older Pd to print an error.
