[Rd] Truncated labels in hist (PR#8864)

[pinard at iro.umontreal.ca]

Hi, people.  Executing the following command:

   hist(rpois(100,5), labels=TRUE)

yields a graphic in which some labels are truncated (on an X11 device).
The truncated labels are those over the highest bars.  The hist function
should ideally manage enough room for the labels, automatically.
(Specifying ylim solves my problem, but yet, hist could be frienlier.)
