IMO, this is only feasible if we also accept command invocation via
"M-x" with spaces instead of dashes (and even then as an opt-in
behavior).  The current behavior has the huge advantage of showing
what exactly you should type to invoke each command, whereas replacing
dashes with spaces loses that important feature.
