The addition here is

	set path to git-http-backend

That reads as if you are telling the reader to do this

	GIT_PROJECT_ROOT => "/var/www/git",
	path => "/usr/libexec/git-core/git-http-backend"

because the descriptions for these two are next to each other and so
similar, but I somehow do not think you meant there is a variable
whose name is `path` (note that I do not use lighttpd and am not an
expert on its configuration---which makes me the ideal guinea pig to
judge if your update makes sense to the target audience).

Do you mean something like

	use `alias.url` to mark that `/git` hierarchy is handled by
	the `git-http-backend` binary (use the full path to the
	program).

I do not see any quoting in your updated text, but many of what the
end-user needs to type literally must be `quoted for monospace`, I
would think.

Thanks.
