[U-Boot] Patchwork breaks commit log format ?

Hello Patchwork developers,

I noticed Patchwork sometimes modifies commit-log in a wrong way.

Please compare the following two:

[1] Original patch I sent: http://lists.denx.de/pipermail/u-boot/2016-October/271173.html

[2] After Patchwork picked it up: http://patchwork.ozlabs.org/patch/687707/

Please see the first line of the commit-log.

In my original patch, the hyphens are aligned as follows:

- Constify UMC setting data arrays - Merge data arrays *_d0 and *_d1. - Add PHY parameters for LD20 C1 board

In the picked up one, the first line went left:

- Constify UMC setting data arrays - Merge data arrays *_d0 and *_d1. - Add PHY parameters for LD20 C1 board

Is this a Patchwork bug?
