DISCUSSION
----------
The patch produced by 'git format-patch' is in UNIX mailbox format,
with a fixed "magic" time stamp to indicate that the file is output
from format-patch rather than a real mailbox, like so:

Typically it will be placed in a MUA's drafts folder, edited to add
timely commentary that should not go in the changelog after the three
dashes, and then sent as a message whose body, in our example, starts
with "arch/arm config files were...". On the receiving end, readers
can save interesting patches in a UNIX mailbox and apply them with
linkgit:git-am[1].
When a patch is part of an ongoing discussion, the patch generated by
'git format-patch' can be tweaked to take advantage of the 'git am
--scissors' feature. After your response to the discussion comes a
line that consists solely of "`-- >8 --`" (scissors and perforation),
followed by the patch with unnecessary header fields removed:

> So we should do such-and-such.
Makes sense to me. How about this patch?

------------
When sending a patch this way, most often you are sending your own
patch, so in addition to the "`From $SHA1 $magic_timestamp`" marker you
should omit `From:` and `Date:` lines from the patch file. The patch
title is likely to be different from the subject of the discussion the
patch is in response to, so it is likely that you would want to keep
the Subject: line, like the example above.
