Please recognize the difference between dimensionless and unitless.
3 ft/in is dimensionless, but it has the unit "ft/in". 
As calc-convert-units is about converting units and (I suppose)
nothing else, there is no need to ask the user here. If the user
entered "kg" as the old unit of "3 ft / in" this makes no sense.

Please, trust the user she knows what she wants. The new behavior is
a regression.
