### Please describe the problem.
When i try to sync to my server (path in .git/config is "[fcb8:b10:1cb8:c94:58d0:2522:89f9:c89e]:/home/thomas/git/musik") the url gets messed up by annex and i get the error "git-annex: bad url ssh://[fcb8/~/b10:1cb8:c94:58d0:2522:89f9:c89e]:/home/thomas/git/musik".

### What steps will reproduce the problem?
1. init git & annex
2. add files
3. add a IPv6 address remote
4. push git branches
5. git annex sync
