Here is an adaptation of Eric's patch that takes these problems into
account. As the target is either a string, the 'delete symbol, or
a function, I test those in turn. In the case it's a function, the
result from the call should be either a string or a 'delete symbol or
a string. In the case it's a 'delete symbole, the hook is called with
'nil' as target.

Eric: I reused your log message, I hope you don't mind.

Best,

Alan
