[PATCH b4] b4: fix from header not using real name

[Justin Stitt <justinstitt@google.com>]

When using `b4 send` there seems to be an issue with the real name not
being included in the From: header.

Here's an example:
| From:	justinstitt@google.com

Whereas, something like the following is preferred:
| From: Justin Stitt <justinstitt@google.com>

This patch fixes this issue and achieves the preferred behavior (above)
by properly using both parts of a user's `from` field from their config.

A .gitconfig like this now properly works
| [sendemail]
|   from = Justin Stitt <justinstitt@google.com>

It should be noted that myself and Nick (reported this issue) use an
internal smtpserver called sendgmr. I'm not sure if this is a non-issue
on other smtpservers but the fix I've outlined in this patch looks
universal for locally-ran smtp commands.
