In PCB, we could put the hook in the HID api; since what we're talking
about here is a difference between a string's "value" and it's
"appearance".  Is there a common point (or at least an easily
accessible point) where we have the string's content just before we
"print" it (display on screen, export to postscript, render in png)?
Those are really the only places we *need* to hook, except perhaps in
gnetlist.
