no-log don't capture error output, just let it flow straight to stderr

no-details only show 'redo' recursion trace (to see more later, use redo-log)

no-status don't display build summary line at the bottom of the screen

no-color disable ANSI color; --color to force enable (default: auto)

debug-locks print messages about file locking (useful for debugging)
