+ * - Reconsider the channel creation after format processing. Current
+ * logic may "bleed" channel names into the analog group when logic
+ * channels' columns follow analog columns (seen with "-,2a,x8").
+ * Trying to sort it out, a naive change used to map logic channels'
+ * data to incorrect bitmap positions. The whole channel numbering
+ * needs reconsideration. Probably it's easiest to first create _all_
+ * logic channels so that they have adjacent numbers starting at 0
+ * (addressing logic bits), then all analog channels (again adjacent)
+ * to simplify the calculation of their index in the sample set as
+ * well as their sdi channel index from the "analog column index".
