> Regarding the use of "exec", which was suggested by Leif, was in my
version of the patch, and is in the current patch: if we want to be able
to do something like `sage --norc -c ...` (as in #11932), then we want to
be able to delete the temporary `DOTSAGE` directory after the Sage command
finishes. Using "exec" prevents this, doesn't it?
Using `exec` '''here''' doesn't prevent that. It just means that we
cannot implement `--norc` itself using `exec`, which is fine.
Example:
scriptA does
{{{
scriptB
cleanup
}}}
scriptB does
{{{
exec scriptC
cleanup2
}}}
The `exec` in `scriptB` doesn't prevent the `cleanup` in `scriptA`, it
only prevents the `cleanup2` in `scriptB`.
