In tests, enforce $PYTHON and *not* /usr/bin/env python or similar:

  $ testrepohg files 'set:grep(r"#!.*?python") and **/*.t' \

  > -X tests/test-check-execute.t \

  > -X tests/test-check-module-imports.t \

  > -X tests/test-check-pyflakes.t \

  > -X tests/test-check-shbang.t

The above exclusions are because they're looking for files that

contain Python but don't end in .py - please avoid adding more.

look for shell scripts that do not use /bin/sh

  $ testrepohg files 'set:grep(r"^#!.*/bi{1}n/sh") and not grep(r"^#!/bi{1}n/sh")'
