Re: [PATCH 2/2] remote.c: reject 0-length branch names

It truly makes no sense because `branch..remote` fits the schema of
`branch.<name>.remote` where <name> is "", but "" isn't a valid branch
name (and it never has been AFAIK). So such a key would never be useful
to Git, and it would be extremely hacky for a non-Git tool to use such
a key.

Yup, we might want to reserve a bogus key or two that can never be a
branch name to allow us express "this configuration is in effect for
all branches" (e.g. "branch.*.rebase = never"), but the natural such
name would be "*" and does not have to be an empty string.
