Documentation
An alist for custom printing of any type.
Pairs are of the form (PREDICATE . PRINTER). If PREDICATE is true
for an object, then PRINTER is called with the object.
PRINTER should print to standard-output using cust-print-original-princ
if the standard printer is sufficient, or cust-print-prin for complex things.
The PRINTER should return the object being printed.
Don't modify this variable directly. Use add-custom-printer and
delete-custom-printer
