The documentation of "git whatchanged" is pretty explicit that this
has retained for historical reasons to help those whose fingers
cannot be retrained. Let's see if they still are finding it hard to
type "git log --raw" instead of "git whatchanged" by marking the
command as "nominated for removal", and require "--i-still-use-this"
on the command line.
While at it, update the documentation page to use the new [synopsis]
facility to mark-up the SYNOPSIS part.
Two test scripts on fast-import run "git whatchanged" without even
checking the output from it. It might still help manual debugging
so I've replaced these calls with "git log --raw", but we probably
are better off removing such useless git operations that do not
contribute to the tests. Such a clean-up is left outside the scope
of this patch.

+WARNING

+`git whatchanged` has been deprecated and is scheduled for removal in

+default; `whatchanged` is not even shorter to type than `log --raw`.
