Comment (by ncohen):

 Hello !

 > For ease of maintenance (and for cleanliness of code, which isn't quite
 as important), it would be best to not duplicate the work, so it would be
 best to have `standard_packages` rely on `sage --standard`, or vice versa.

 +1

 > My strong preference is for `sage --standard` to ''not'' rely on
 `standard_packages`, since `sage --standard` should work without having
 built Sage.

 That's what I tried first, i.e. fix `sage --standard`. But then you have
 some problems, like undefined environment variables, and you must re-parse
 everything in `standard_packages` again.

 I thought a bit about making this script dependent on sage, and I actually
 ended up wondering whether .... we need those `sage -standard` scripts.
 Right now they are totally broken, and... Well, if we do not need them
 then perhaps we should stop maintaining them.

 > (In my brief tests, by the way, this does fix the Sage functions as
 intended. But I haven't looked at the actual changes to see if they make
 sense.)

 I hope that they do `;-)`
