Apparently, this has already been implemented in GnuPG 2.1, but not in
GnuPG 2.0 nor 1.4:

http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=commit;h=54591341
http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=blob;f=g10/getkey.c;h=ad7e71cf7ddca38a917756b8a0675b665c3eddec;hb=54591341#l2565

Maybe good to update the documentation and possibly backport it to other
branches?
