[PATCHv3 2/4] Documentation/clone: document ignored configuration variables

["SZEDER Gábor" <szeder.dev@gmail.com>]

Due to limitations/bugs in the current implementation, some
configuration variables specified via 'git clone -c var=val' (or 'git
-c var=val clone') are ignored during the initial fetch and checkout.

Let the users know which configuration variables are known to be
ignored ('remote.origin.mirror' and 'remote.origin.tagOpt') under the
documentation of 'git clone -c'.
