Re: help-echo in Custom

[Per Abrahamsen]

Since I'm CC'ed:  

I believe :help-echo in widget.el existed before the help-echo text
property.  When Emacs got the property, someone made sure widget.el
set it with the value given.  Which works fine for the simple case of
a string, where the two API's are identical.

The correct solution would probably be for the code to carefully
translate the argument to :help-echo into the format expected by
help-echo, probably by creating a helper function on the fly.
