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.
Actually, that appears to be exactly what is done. What confused me
was that the Elisp manual suggests that the rules for correct
arguments to :help-echo are exactly the same as for 'help-echo values.
I have no problem with them actually being different, as long as that
would be clearly mentioned in the Elisp manual. The usual arguments
to 'help-echo make indeed no sense in the case of widgets.
The only change I suggest (apart from the change in the Elisp manual)
is to allow expressions that evaluate to strings in :help-echo, as
they are for `help-echo values. This is easy to do by making the
minor change in `widget-echo-help' I suggested. Otherwise, authors
who only check their code using mouse-over are going to believe such
arguments work anyway, whereas with the present version of
`widget-echo-help', they do not work with <tab>.
Sincerely,
Luc.
