Thanks for pointing this out. My review time is severely limited these
days so I didn't go the distance of re-studying and re-digesting which
function was the correct one to use.

Agreed. Specific to the "established previously" I wrote above, I was
referring to [1] from just a few days ago which explained why 'return
-1' was preferable to die() in a similar case that had an odd mix of
'return -1' and die() in the same function.
