clone: reword messages to match the end-user perception

When cloning into a non-bare repository, e.g. "git clone $URL mine",
we used to report that we are cloning into "mine/.git".  Reword the
report to say "Cloning into mine" instead, as that matches what the
end-user asked for closer.

Make the message for "git clone --bare $URL mine" to say "Cloning
into bare repository mine" do make the distinction between this case and
the above stand out a bit more prominently.
