Why is this a bug?  The characters which are "conflated" are pairs of
lower-case and upper-case characters, upper-case characters in which
Emacs decapitalizes when modifiers aside from Shift are depressed, so
that commands bound to lower-case characters with modifiers are executed
even if latches such as Caps Lock are activated.
