I do not see any problem with the plain numerical parameter to vol being
the multiplier. There is no scope for accidental phase shift - simply
use positive numbers only. Obviously the shift for negative parameters
is only 180 degrees, i.e. inversion. Which is what the man page states.
Plus it provides mechanism for waveform subtraction which is a very
useful feature. I see absolutely no problem with the current behaviour.

If you find the manpage misleading (not in my case, though), please send
a patch to the manpage source code you deem appropriate.
