Format specification docs for signs and zero values is unclear

[seanmiddleditch]

The format specification mini-language documentation on the website states:

Option	Meaning
'+'	indicates that a sign should be used for both positive as well as negative numbers.
'-'	indicates that a sign should be used only for negative numbers (this is the default behavior).
space	indicates that a leading space should be used on positive numbers, and a minus sign on negative numbers.

The use of "positive" here should perhaps instead say "nonnegative" since they affect zero values.

e.g., format("{+}", 0) produces "+0", but the documentation as written could be interpreted as expecting the result to be "0" with no sign.
