full range of values for each of the integral signed and unsigned
array types.
This closes SourceForge patch #100506.
'verbose' flag ala GvR updated test harness architecture.
Old way:
verbose = 0
if __name__ == '__main__':
verbose = 1
New way:
from test_support import verbose
Some other small readablility and functionality updates.
