Actually, I found another program that does what I want.  urwid
( has a input_test script that echos
all the keystrokes.  In this script, only one mouse scroll event is
reported per scroll.  So I don't know where the bug is at this point
(though I am convinced that it is indeed a bug somewhere).  Here's the
iTerm2 bug I reported if anyone's interested
