[PATCH] Fix git-archimport on empty summary

[Paolo Bonzini <bonzini@xxxxxxx>]

I got this while importing bonzini@xxxxxxxxxxxxxx/lightning--stable--1.2 
(archive available at 
http://www.inf.unisi.ch/phd/bonzini/webdav/bonzini@xxxxxxxxxxxxxx via 
webdav).

The patch seems pretty obvious to me, and Martin Langhoff has already 
seen it in private e-mail.

Thanks,

Paolo
