On RP2040: $help reports two double-word topics, but "$help Control signals" gives no response (whereas "$help Control" IS responsive)

[TPMoyer]

The two double-word topics ("Control signals" and "Tool change") reported by $help do not work as "$help topicNameHere".
One might:

1. change the topics reported by $help to include only single word topics (ControlSignals and ToolChange) to match the setting_detail_t entries in settings.c
   or
2. modify the report.c to trim the XXX in $help XXX to be only a single word, then parse the "$help topic" response based thereupon.

One might also wish to futureproof against what might turn out to be an unintentionally set trap.
This is related to the CamelCaps implementations of the topics reported, and their AllMoSt matching entries in the setting_detail_t instantiations.
Control signals
Tool change
vs the setting_detail_t entries in settings.c as
Group_ControlSignals
Group_Toolchange

Control signals might become ControlSignals
Tool change might become ToolChange
Group_Toolchange might become Group_ToolChange

I went for option 2.
