[Ifeffit] data processing - not all columns are visible

It's been a busy week -- sorry for the pokey response.

Erik is correct on all fronts -- the problem is the length of the line
of column labels.

One rather irksome work-around I can suggest is to remove that line
with a text editor.

The better work-around Erik alludes to is part of the newest version
of my software.  However, I do not yet have a Mac installer for the
new version.
