commit fb7f4cb973abc9f5eb05eb240607be35c1be986c
Author: Tobias Mueller <muelli at cryptobitch.de>
Date:   Thu Dec 1 21:15:12 2016 +0100

    python: Define a macro for wrapping fragile result objects.
    
    * lang/python/gpgme.i (wrapresult): New Macro.
    --
    
    This reduces the amount of copy and pasted code at the expense of a
    slightly more complicated logic with a macro.
