path_line() builds a PathLine from path_text's exact vocabulary (verified
character-for-character in tests), wrapped() carries the composer's
insertion cursor — riding the trailing arrow when its seam is the line
break — and conftest pins MESHTERM_POWERLINE=0 so screen assertions never
depend on which terminal runs the suite.
