Yes, kbd should have been defined as an alias of read-kbd-macro
(i.e. a function) and mark it as pure so the byte-optimizer can
precompute it when applicable.

I know that changing a function into a macro introduces many
compatibility problems, but maybe changing this macro into a function
can be done without problems?
