// The code below this function goes on a hunt for services based on the metadata
// that has been passed in. Occasionally, it will find more than one matching
// service. In some scenarios (e.g. multiple identically-named .desktop files)
// there's a need to pick the most useful one. The function below promises to "sort"
// a list of services by how closely their KService::menuId() relates to the key that
// has been passed in. The current naive implementation simply looks for a menuId
// that starts with the key, prepends it to the list and returns it. In practice,
// that means a KService with a menuId matching the appId will win over one with a
// menuId that encodes a subfolder hierarchy.
// A concrete example: Valve's Steam client is sometimes installed two times, once
// natively as a Linux application, once via Wine. Both have .desktop files named
// (S|)steam.desktop. The Linux native version is located in the menu by means of
// categorization ("Games") and just has a menuId() matching the .desktop file name,
// but the Wine version is placed in a folder hierarchy by Wine and gets a menuId()
// of wine-Programs-Steam-Steam.desktop. The weighing done by this function makes
// sure the Linux native version gets mapped to the former, while other heuristics
// map the Wine version reliably to the latter.
// In lieu of this weighing we just used whatever KServiceTypeTrader returned first,
// so what we do here can be no worse.
