A mess, to be sure. Fortunately it was easy to fix; the fix is now
in git.
When the bundle-print function of a package is invoked via the GUI,
we know perfectly well it's a function call and nothing to do with
lags of a series that a trickster may have created. We just weren't
conveying that knowledge to "genr"; now we do.
