+-m::
+ By default, differences for merge commits are not shown.
+ With this flag, show differences to that commit from all
+ of its parents.
+
+ However, it is not very useful in general, although it
+ *is* useful on a file-by-file basis.
+
+Examples
+--------
+git-whatchanged -p v2.6.12.. include/scsi drivers/scsi::
+
+ Show as patches the commits since version 'v2.6.12' that changed
+ any file in the include/scsi or drivers/scsi subdirectories
+
+git-whatchanged --since="2 weeks ago" -- gitk::
+
+ Show the changes during the last two weeks to the file 'gitk'.
+ The "--" is necessary to avoid confusion with the *branch* named
+ 'gitk'
