git am lets you put the lines in the order From: then Subject: as well
as Subject: then From:, which this commit message suggests your patch
doesn't allow.

+def find_author(comment):
[...]
+    if first_line.startswith('From:'):
+        author_line = first_line
+    elif (first_line.startswith('Subject:') and
+          second_line.startswith('From:')):
+        author_line = second_line

It seems kind of ugly that find_author() has to explicitly know
about the complete set of header lines that we're happy to extract
from the body. This just about works for two header lines, but
I think it would quickly get unwieldy if we get to three or four
headers which might all be in any order...
