We generate multiline constraints whenever versions are different
between python 2 and 3 for the same package. That was happening when I
wrote the tool in the first place - it was one of the reasons I wrote
edit-constraints, to avoid writing silly-awkward sed. (A multiline
constraint when sedd'd will error with 'requirement already supplied'
or whatever the pip error string is.

Yes. And/or do the long mooted refactoring to separate out the scripts
from the current constraints and requirements.
