Sure, will do.

That could be a bit tricky since Pinentry is not called with such
information, but perhaps it might be possible by sending context
information through the special envvar PINENTRY_USER_DATA.  I have just
proposed a patch to Pinentry for that.

If public key encryption were used, the buffer would contain something like:

    Please enter the passphrase to unlock the OpenPGP secret key:
    "Daiki Ueno <ueno@unixuser.org>"
    4096-bit RSA key, ID C8C530D6,
    created 2010-02-04 (main key ID D7E69871).

For the case like the above, we could hide the buffer (though this is
also a bit tricky since the strings may be translated in user's native
language).
