I threw some of the sorting of the (otherwise great) chapter on operators about a bit.
The version I edited followed the convention of the old manual of putting "new" and "!" (not) in the same section as operators that take only a single input and put "-" (minus) in with those. I moved "!" to the logical operators section, explaining that it's a exception there (in taking a single argument), put minus in with the math as a side-note (where I feel it belongs) and elaborated on "new" in relation to "@".
My reasoning here is that in a older version of the pdf "new" was only mentioned as being similar to "!" in taking a single argument and this was -at the time- extremely confusing to me as -aside from this- "new" is nothing like "not" at all. "not" has been a elementary logical operation since at least Frege, it's the only (non-trivial) single argument operation in binary logic; it belongs in there.
I'm -again- open for debate here, but a sectioning based on role and function makes a lot more sense to me than the old sectioning based on the number of arguments.
Just pointing this out because I don't want to arbitrarily throw stuff about without justification.
While I was at it I added "~" (bitwise invert) that wasn't previously documented aside from Stefan's helpful note on the WiKi.
