[PATCH] branch -v: align even when the first column is in UTF-8

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Branch names are usually in ASCII so they are not the problem. The
problem most likely comes from "(no branch)" translation, which is in
UTF-8 and makes length calculation just wrong.

 So far all git translations are utf-8 compatible. Branch names may
 use filesystem encoding, but then packed-refs specifies no encoding.
 Anyway branch names should be in utf-8.. at least internally, imo.
