Re: [PATCH] submodule: Fix documentation of update subcommand

[Junio C Hamano <gitster@pobox.com>]

I did a bit more digging of the history, and came up with this,
which would be with a clearer and fairer description.  Also to
clarify, I spelled what Michal's "This" meant to refer to.

Subject: [PATCH] submodule: clarify documentation for update subcommand

e6a1c43a (document submdule.$name.update=none option for gitmodules,
2012-05-10) meant to say "Unlike the case where your .update
configuration is set to either 'rebase' or 'merge', when it is set
to 'none', the tip of the submodule would never move.  You can use
the --checkout option if you want the contents of the submodule to
be updated to some other commit."

But the resulting text made it sound as if using "--checkout" would
have no effect when .update configuration is set to 'rebase' or
'merge', which was misleading.  In fact, with the "--checkout"
option, the tip of the submodule moves to the exact commit that is
recorded in the superproject tree, regardless of .update
configuration.
