[PATCH v2 0/3] Better ref summary alignment in "git fetch"

v2 reformats "abc/common -> def/common" to "{abc -> def}/common" instead and fall back to "a -> b" when they have nothing in commmon (e.g. "HEAD -> FETCH_HEAD"). We could add an option if a user wants to stick with "a -> b" (and we could do some alignment there as well) but it's not part of this series.

It's a shame that the flag '-' in these ref update lines is not the same in fetch and push (see 1/3). Because git-fetch does not support --porcelain option, maybe it's not too late to change its meaning...
