I do not have particularly a strong opinion, but I think it is very
sensible to call the value given to the option "--reference" with a
phrase that is not just "repository".

As the command line of "clone" must name one repository (i.e. the
one which we clone from), and its "--reference" option must name
another repository as its value (i.e. the one that we borrow from in
order to reduce the object transfer), calling both <repository>
makes it easier to confuse readers unless the writer carefully makes
sure that <repository> in the desription is unambiguous and it is
clear which one of these two repositories is being discussed by the

I just re-read the existing Documentation/git-clone.txt and looked
for "reference".  All uses of "reference repository" in the prose
made sense and I found it would not be an improvement if any of them
is replaced with just "repository".  It may be helpful to add
something like:

	 --reference[-if-able] <repository>::
	+	Define a repository (reference repository) to borrow
	+	objects from.  
		If the reference repository is on the local machine,

to define which repository we mean by that term, though.
