Repeating the keys should start calc up normally.
But `calc-dispatch' followed by "`" or "M-`" normally starts
calc-embedded-edit, and which behavior is used depends on whether or
not the `sit-for' is interrupted or not.
If the `sit-for' is interrupted, then a subsequent call of
`this-command-keys' gets a longer string than if `sit-for' isn't
interrupted.  I don't know what good the `sit-for' is doing; calc
shouldn't behave differently depending on how fast those keys are
pressed.  
The behaviour without the `sit-for' seems the proper behaviour;
perhaps the `sit-for' should be removed.
