Please make it “Fixes <https://bugs.gnu.org/25035>.” so we can more
easily grep the git log.

Did you identify the part of the code that invokes “python”?  If so,
instead of adding a wrapper, we could patch that file to use the
absolute file name of “python”, which would be even better.

Anyway, congrats on finding out what was wrong!

Thanks,
