Correct. You can point your gpg.program configuration variable at your wrapper, perhaps

    $ cat >"$HOME/bin/mygpg-with-pinentry" <<\EOF
    #!/bin/sh
    exec gpg --pinentry-mode loopback "$@"
    EOF
    $ chmod +x "$HOME/bin/mygpg-with-pinentry"
    $ git config gpg.openpgp.program "$HOME/bin/mygpg-with-pinentry"

or something like that.  It is unfortunate that

    $ git config gpg.openpgp.program "gpg --pinentry-mode loopback"

does not work.
