I'll echo Tom's complaint in a nearby thread that the format of these
complaints is distinctly lacking.

But I do agree that this looks at least a bit fishy - if there were an
ispell file without a "flag" line, it does indeed seem that we'd pass an
uninitialized flag to NIAddAffix(), which'd duly cpstrdup() it.

Now, practically that's probably fine, because there's likely to be no
affix files witout flags, but we shouldn't rely on that.
