Yes you are right (I already said that it works, see above).  I
_thought_ that 'ask is more typical as 'query in Emacs and therefore
it's preferable to use it.  Grepping[1] the sources shows that 'query
is used two times (`checkdoc.el', `sendmail.el') and 'ask 11 times,
i.e. not so clear as I expected. ;-) Is there a coding convention for
'ask vs. 'query?

BTW, now I learned from (info "(elisp)Composite Types"), what's the
difference between (const :tag "Ask" foo) and (other :tag "Ask" foo)
in defcustom. :-)

Bye, Reiner.
