library/pprint.m:
Clean up this file a bit, to make future merges with the
mode-constraints branch easier.
Add special casing for variables and sparse bitsets, since these can be
useful.
Group predicates and functions logically.
Put the casting predicates and the *_to_doc functions for the special
cases in the same order as the special case tests in to_doc itself.
Shorten excessively long dividing lines.
tests/hard_coded/pprint_test.{m,exp}:
A new test case to test the new additions to to_doc.
tests/hard_coded/Mmakefile:
Enable the new test case.
