dwim runs what "sfdupes scan /" runs with no flags, then what "sfdupes trees" runs, and ends with a stderr line saying that "sfdupes trees" prints the report again. An interrupt or fatal scan error ends it before the report, as scan ends. It catches signals only during the scan, so a signal during the report ends it at once, as it ends trees. Model: opus-5-5
