I still find it strange.

So, OK, repeating calc-dispatch key fast does indeed send current line
to some kind of "Calc edit mode"... but only if I *have not* opened calc
before. Once I do "M-`" slowly *once*, it subsequently works even when
typed quickly.

Honestly, it really does look like a bug to me -- at the very least we
should strive for some kind of consistent behaviour.

Exactly what calc-dispatch tries to do depends, I think, on what key is
it bound to... it seems like second (quick) keypress is interpreted
according to what calc-dispatch-help, but a second keypress after a
pause wants to toggle calc. Any chance of making this "deliberate
behaviour" customisable?
