"""Unit: docker backend `_provision_git_user` (issue #86).

Mocks `bottle.exec` / `bottle.cp_in` and asserts on the script
strings and user parameter. The cwd + git-gate passes are covered
indirectly by the existing integration-shaped tests in
test_smolmachines_provision; this file targets just the git_user
pass."""
