OptionalwrapAllow the signature to wrap onto more than one line.
false — one line, as the editor's floating bar needs (it ellipsizes what does
not fit rather than growing).
true for a signature laid out in a fixed-width panel, where a long one (PV(rate, nper, pmt, [fv], [type])) should use the second line instead of a horizontal scrollbar. Wrapping also
switches the separator's trailing space to a breaking one, so a line ends after rate, rather
than starting with the comma of the argument below it.
The caret's function context — drives the name + which argument is emphasized.
