Re: [Gretl-devel] smpl <condition> --restrict --permanent

By popular request we introduced (in gretl 1.9.91) the --permanent

So here's my proposal: in the circumstances described above, if
you issue a command to shrink the dataset permanently, gretl checks to see
whether all saved models fall under the "easy case". If so, fine. If not, you
get a warning that not all saved models can be preserved, with a "Go ahead?
Yes/No" dialog. If you say "Yes", we destroy all the models that would
turn into zombies.
Any comments/suggestions?
I'm ok with this. We may offer the option to save them automatically as
bundles so that if you depserately need to retrieve essential stuff from
the (eg coefficients, covariance matrices), you can always do so from the
xml files.
