Point taken.

What I really meant was wrt dropping the Shift modifier. Read-key-* has no
trouble knowing to stop after one key, if that key is undefined. For
example, if C-M-+ is undefined, it returns this: [-67108821]; it doesn't ask
itself when to stop.

Otherwise (a key sequence is defined), it continues to read until it gets
the complete key sequence. I would expect it to have such behavior all the
time, and not make an exception of Shift. That's all.

IMO:

 - read-key-* should not drop the Shift modifier: if Shift-* is undefined
and * is defined, it should act as it does with any other undefined key
sequence (return Shift-*), instead of returning *
 - if read-key-* does drop the Shift modifier, then this should be
documented
 - read-key-* should in any case optionally be able to not drop the Shift
modifier
