The above justification is not a sufficient reason to stop giving
helpful advice when someone uses an option that was historically
supported:

Luckily the support was removed 4 years ago and I don't think anyone
is going to run into this, so a different justification could apply.

	Support for the git am -d/--dotest option was removed four years ago
	(see e72c7406, "am: remove support for -d .dotest", 2008-03-04) and
	presumably no one is trying to use it any more.  Simplify the
	code and free the short-and-sweet "-d" option for other uses by
	no longer parsing it.

	The motivation: xgettext copes poorly with messages starting
	with '-'.  Rather than fixing this ancient message, let's take
	this as a reminder to remove it.

See http://thread.gmane.org/gmane.comp.version-control.git/75896 for
context.  Though also see

Hope that helps,
