Do you mean it is a bad idea to support or a bad idea to make use of such support?

I suggested --no- for consistency with current git commands that use parseopt. But on second thought, I agree that it be confusing for

	--prefix=foo --no-prefix

to mean something different from no --prefix parameter at all.

The documentation says

	--prefix=<prefix>

...

		Before Git 2.0, the default prefix was "" (no prefix).
		This meant that ...

which suggests that I can use --prefix="" to mean no prefix. Perhaps it needs a note to suggest using '--prefix ""' instead?

Thanks, Jonathan
