In the case of piano, the e should be released/restruck at the second e, but 
not released again until the first e cuts off. To properly implement that, 
you would have to either keep track of how many notes are active so that you 
only fully release the key after there are no occurrences of that note still 
active, or you could keep track of when the last note will turn off based on 
notelengths and the time they started.

You are right that << e1 \\ { c4 d s f } >> isn't what you meant for it to do, 
but neither is << e2 \\ { c4 d e f } >>. a view of what is going on, from the 
view of the 'e', helps show that:
What it seemed to be doing was {e1}
What you say you wanted it to do was {e2 e4}
What your original expression represented was {e2 e2}

The sustain pedal could influence wether or not to cutoff at points too, but I 
thought midi has distinct pedal support.
