commit 2d1d795481bc011447284f8ce0a3ae96a08daf17
Author: Neal H. Walfield <neal at g10code.com>
Date:   Fri Feb 19 15:52:08 2016 +0100

    gpg: Systematically detect and fix signatures that are out of order.
    
    * g10/keyedit.c (sig_comparison): New function.
    (fix_key_signature_order): Merge functionality into...
    (check_all_keysigs): ... this function.  Rewrite to eliminate
    duplicates and use a systematic approach to detecting and moving
    signatures that are out of order instead of a heuristic.
    (fix_keyblock): Don't call fix_key_signature_order.  Call
    check_all_keysigs instead after collapsing the uids.
