[PATCH] clone: Add the --recurse-submodules option as alias for --recursive

[Jens Lehmann <Jens.Lehmann@web.de>]

Since 1.6.5 "git clone" honors the --recursive option to recursively check
out submodules too. As this option can easily be misinterpreted when it is
added to other commands like "git grep", add the new --recurse-submodules
option as an alias for --recursive so the same option can be used for all
commands recursing into submodules.

Fine by me, then what about this patch?

And am I right to assume that there are no objections against using
--recurse-submodule for fetch, checkout & friends?
