Hi Mike,

This is due to a deficiency at mercurial. On git, there are two concepts on
their meta-tags: patch author and committer. Unfortunately, mercurial has only
one meta-tag: user.

When a patch is cherry-picked, mercurial will use the current user as his
"user" meta-tag. This indicates who applied the patch at the mercurial tree.

In order to preserve both information on our tree, we are using the "user" meta
tag for the "committer", and the "From:" field at the patch description as the
patch author, as stated at README.patches.

The committer info is important to allow us to see from what tree a patch came.

The -git conversion scripts properly handle the From: info when giving the
credits for the patch.

Cheers,
Mauro
