[Ifeffit] Plot Labeling bug in Athena

[Matt Newville]

Hi Paul,

Thanks -- I think this is probably a core ifeffit plotting
problem, and isn't specific to athena.  I've recently noticed
similar cases of 'the last thing drawn is missing from
hardcopies', especially text and "keys" for the legend.  I'll
look into the root cause.  I believe a simple workaround would
be to repeat the last plot() command before making hardcopies.

On a related subject, there are also definitely major problems
with all plotting on Windows.
