I do recall seeing this change and remember wondering what the
fallout from this change would be.  So relative to the previous
round, the above is a definite improvement to clearly state that no
test that is currently in the codebase is affected by this change.

As to the change itself, I do not much care among (1) what this
patch does, (2) doing nothing, or (3) barf when the action is not a
pick.  At least, having this step separate from other changes like
this round of the series does is a very good thing---when somebody
with more knowledge and stake in what the fake-editor does appears
and explains why forcing pick is a good idea, we can easily revert
only this step.

Will queue as-is together with the other two patches.

Thanks.
