local clone requires absolute path

[fhs]

git converts the relative path to an absolute one:

$ git clone one two
Cloning into 'two'...
done.
$ cd two/
$ git remote -v
origin	/tmp/one (fetch)
origin	/tmp/one (push)
$ git pull
Already up to date.

However with gig it's not converted:

$ gig clone one two
Enumerating objects: 3, done.
Counting objects: 100% (3/3), done.
Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
$ cd two
$ git remote -v
origin	one (fetch)
origin	one (push)
$ gig pull
Error: repository not found

I'd rather fix this in go-git, especially since the function to check for local URL is part of an internal package.
