There are two practical problems with this.
1) quilt does not force any authorship information to be preserved,
   in the description, so this probably a common case.  Although for
   most users just needing to specify --author sounds reasonable.

2) There are currently 84 out of roughly 1322 patches in
   2.6.17-rc4-mm1 that git-mailinfo cannot compute the author for.
   Generally the information is there but in such an irregular form
   that it cannot be automatically detected.

   If we can resolve that problem I am willing to make it an error.
   If we can't then sucking quilt patches into a git tree is much
   less useful.  

   Given the ugliness in -mm making it an error to have an
   non-attributed patch would result in people specifying --author
   when they really don't know who the author is, giving us much
   less reliable information.

   Possibly what we need is an option to not make it an error so that
   people doing this kind of thing in their own trees have useful
   information.


The list of patches that git-mailinfo cannot find authorship
information for from 2.6.17-rc4-mm1 is included below.  Mostly these
are either git trees splatted into a single file, or simply fixes
added by Andrew.  But there are some like: gregkh-usb-usb-gotemp
that have no description at all and only the patch name records who
made the patch.

A really ugly case is acx1xx-wireless-driver patch, which
appears to have multiple authors and a serious history
before Andrew got it.
