I'm afraid I don't have much time to think about this.

My suggestion is to add an option to `read-key` which makes it ignore
`function-key-map` and all other hardcoded remappings that are only
applied when a key sequence is not bound (i.e. those remappings which
could/should conceptually be applied by `function-key-map` but aren't
for various historical/technical reasons, such as dropping `down` events,
demoting `drag` events, downcasing letters, ...).

At the level of `read-key-sequence` this should use the
`dont-downcase-last` argument (since `read-key` only reads one event,
it's OK if `read-key-sequence` only applies it to the last event).
