  # One mimetype=desktopfile pair per line: the semicolon only separates
  # multiple desktop-file candidates for the SAME key, it doesn't chain
  # separate mimetype=value pairs on one line — mimeapps.list parsers
  # (verified against xdg-utils' own xdg-mime script) match by scanning
  # for a line that STARTS WITH "mimetype=", so cramming several pairs
  # onto one semicolon-joined line silently hides every key after the
  # first from ever being found.
