[PATCH] pwclient: support 'git am -m'

[Greg Kurz]

A new '--msgid' argument is added that causes pwclient to call
'git am -m' and thus add the Message-ID header to the commit
message. This is a recommended practice in some projects like
QEMU for example.

This can also be controlled from the .pwclientrc file, like
'--signoff' and '--3way'.

Hi,

This is a patch against the master branch of pwclient repo at:

https://github.com/getpatchwork/pwclient.git

If it should be submitted some other way, please advice.

Cheers,
