+--stat[=<width>[,<name-width>[,<count>]]]::
        Generate a diffstat.  You can override the default
        output width for 80-column terminal by `--stat=<width>`.
        The width of the filename part can be controlled by
        giving another width to it separated by a comma.
+       By giving a third parameter `<count>`, you can limit the
+       output to the first `<count>` lines, followed by
+       `...` if there are more.
++
+These parameters can also be set individually with `--stat-width=<width>`,
+`--stat-name-width=<name-width>` and `--stat-count=<count>`.
