Well, it's already in the documentation, just scattered around a little...

A compact reference might be useful...

No, it is a vector, and each vector component can be any value, negative
values included.

This: turbulence 0.6
Is a shorthand for this: turbulence <0.6, 0.6, 0.6>

This is also a valid turbulence vector: turbulence <11.4, 0, -3>

No. Generally commands are not dependent on each other if it is not
mentioned in the documentation. If they had to mention everything that is
*not* dependent on each other, there would be no end to it!

Not true.

There are really many of the command that have no limits at all. Probably
more than you think (judging from what you said about turbulence).
