setKey documentation and occurrences not up to date

[Hovestar]

In the documentation for setKey (https://harbour.github.io/doc/harbour.html#setkey) it mentions a 3rd param that is a condition on when to return the codeblock. If the condition is false SetKey() returns false rather than nil and the documentation doesn't reflect this. This then leads to a few bugs in the source:
An example of it being done well is E:\harbour\contrib\gtwvg\class.prg:553 which checks isblock.

Bugs:
In src\rtl\achoice.prg:129 there's this CASE ( bAction := SetKey( nKey ) ) != NIL.
In contrib\gtwvw\tests\demo.prg:1029
There may be some things related to FUNCTION CSetKey in contrib\hbct\ctmisc.prg
In contrib\hbct\getsecrt.prg:127
In contrib\hbmisc\hbedit.prg:288 Which does it right on line 360
