[PD-dev] [pure-data:bugs] #1243 tabread4~ doesn't correctly deliver first or last sample

[Alexandre Torres Porres]

I always thought it wouldn't hurt to have a linear interpolation at the end
or beggining of the table and would allow us to check these values.

I wish this would be incorporated in vanilla

thanks
