The problem seems to be more general than that -- it doesn't warn about
the wrong number of arguments, ever, if using aliases?
Test case:
(defun foo ())
(defalias 'bar 'foo)
(defun zot ()
(bar t))
(defun foobar ()
(foo t))
----
Compiling file /tmp/warn.el at Fri May 28 02:26:55 2021
In foobar:
warn.el:6:4: Warning: foo called with 1 argument, but accepts only 0
----
Note -- no warning from the zot function.
It seems so odd that nobody has pointed this out before, so I'm
wondering if I'm just doing something obviously wrong in this test
case. Anybody?
