Oh, I see now.

I guess that means the intended justification is the following?

	The git am -d/--dotest option has errored out with a message
	since e72c7406 (am: remove support for -d .dotest, 2008-03-04).
	The error message about lack of support was eliminated along
	with other cleanups (probably by mistake) a year later by
	removing the option from the option table in 98ef23b3 (git-am:
	minor cleanups, 2009-01-28).

	But the code to handle -d and --dotest stayed around even though
	ever since then it could not be tripped.  Remove this dead code.

	Noticed because the error message starts with a '-' and
	xgettext does not cope well with that.
