/**
* Expert editor for /etc/dstarrepeater (D-Star modem driver config).
*
* The on-disk file is a flat key=value (no [section] header), but the
* editor parses it via parse_ini_file() — so we synthesise a temporary
* `[dstarrepeater]` header on read and `sed -i` it back out before the
* file is committed. Otherwise follows the standard Pi-Star
* copy-via-/tmp / mount-rw / restart pattern; daemon:
* dstarrepeater.service.
