Hello,
when applying the mail below (without the '> ' prefix) using git am
--scissors the result looks like:
$ git show
commit 26ef0606927cc1979faa4166d7f9f3584b5cdc61
Author: Tony Lindgren <tony@xxxxxxxxxxx>
Date: Tue Oct 6 05:36:17 2015 -0700
memory: omap-gpmc: Fix unselectable debug option for GPMC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug")
added a debug option for GPMC, but somehow managed to keep it unselectable.
[...]
$ git version
git version 2.6.0
The obvious improvement is to strip all headers like git am does without
--scissors.
If someone wants a bounce of the original mail, just ask per PM.
Best regards
Uwe
