[PATCH] Disallow empty GIT_AUTHOR_NAME or GIT_COMMITTER_NAME

Attempt normal methods for determining user name if GIT_AUTHOR_NAME or GIT_COMMITTER_NAME is set to the empty string. Then fall back to using the user login name.

Previously, if these environment variables were set to the empty string, a message would be printed complaining about missing gecos information. In this case the gecos information was never checked.

This still allows an empty GIT_AUTHOR_EMAIL or GIT_COMMITTER_EMAIL. Possibly someone would want to use these variables to disable the respective email address string?

Trivial one-liner. I made this patch against master, not on top of my previous patch. I assume this is the preferred way.

In case anyone is interested, I am submitting this using thunderbird by the following method.

Set thunderbird config variables according to SubmittingPatches doc.
i.e.:
   Compose messages in HTML format
   mailnews.send_plaintext_flowed  => false
   mailnews.wraplength             => 0

Then I send the patch to myself using git-format-patch and then git-send-email. These two format the patch appropriately for submission and allow me to set the message-id.

Then I select the message, right-click and choose "Edit As New...", edit, select the recipients, and send. I also now have a record of the sent message which I would not have if I used only git-send-email.
