[Rd] incomplete description of return value of stats::uniroot()?

[Georgi Boshnakov]

The "Value" section in the documentation of stats::uniroot() mentions component "init.it" of the returned result:

> "... Further components may be added in future: component \code{init.it}  was added in \R 3.1.0."

I don't see "init.it"  described anywhere in that help page. It is technically not an omission, since the description says "at least the following components...", so maybe it is absent on purpose?

>From my reading of the source something like the following could be added to src/library/stats/man/uniroot.Rd, before the sentence quoted above:

\code{iter} includes the number of iterations, if any, done initially to ensure opposite signs at the ends of the interval.
This number is available separately in component \code{init.it}. If no extension of the interval was attempted, \code{init.it} is set to NA.
