git am mangles commit author name.

Hi all,

Have a problem with git am. I am trying to apply a patch (created with
git format-patch) that I have in a file.
The file contains the line (along with the rest of the patch, of course):
From: username <emailaddress>

So I do the following: git am --signoff < patchfile.patch It applies just fine, but the commit author shows in in git log as: emailaddress <emailaddress> (i.e., the username is nowhere to be seen)

I'm using the latest git release, 1.7.1.1, on ubuntu intrepid.

Would anyone happen to have some suggestions as to what i'm missing, and how I can get git am to properly treat the commit author name?

Thank you all in advance, Daniel
