the man page for sys.calls(), sys.frames(), sys.parents(), etc. lists
sys.nframe() and sys.function() in the usage section (and sys.nframe()
shows up in the examples), but they are never mentioned in the text of
the man page.

my suggested text for sys.nframe is, "sys.nframe returns the current size
of the frame stack, i.e., the frame number of the caller."  i have no idea
what sys.function does.

i believe this should be "accept integer values for the argument which", and
"Non-negative values of which are normal frame numbers"
