John, did you consider using git export for obtaining a source tree that
can be used for headers_install and the following comparison, instead of
git stash+checkout?  AFACS the script does not depend on any other git
functionality than providing a specific version of the source tree.  I am
pretty sure that leaving the original working copy in its original state
is supporting the script's popularity.

Kind regards,
