Couldn't branch->remote_name or remote->name be NULL here?

I think remote->name would be the same as the URL given on the command
line (i.e. no risk of being NULL), and has_merge would be false even when
branch.<name>.merge is specified if branch.<name>.remote is missing
(i.e. no risk of running this strcmp() to begin with), but the latter
safety guarantee is a bit too subtle for my taste to go without a in-code
comment.

Thanks.
