Fix a bug that left branches tracking a dead branch if both their parent
and grand-parent were left with no changes after a "rebase-update" step.
Given the following initial state:
$ git map-branches -v
origin/master
a
b
c * [ ahead 1 ]
without this patch, a "git rebase-update" on this tree state would
leave the branch "c" as tracking a non-existing branch "a":
$ git recursive-rebase
a up-to-date
b up-to-date
c up-to-date
Reparented c to track a (was tracking b)
Deleted branch b (was 448d1da).
Deleted branch a (was 448d1da).
$ git map-branches -v
{a:GONE}
c *
with the patch, we record that the branch "c" is tracking must be
updated twice and we end up in a state were "c" is correctly tracking
"origin/master":
$ git recursive-rebase
a up-to-date
b up-to-date
c up-to-date
Reparented c to track origin/master (was tracking b)
Deleted branch b (was 448d1da).
Deleted branch a (was 448d1da).
$ git map-branches -v
origin/master
c * [ ahead 1 ]

In git version 2.4 the git branch command prints "* (HEAD detached at"
or "* (HEAD detached from" instead of "* (detached from". Adjust the parsing to make our tests
still work with git 2.4.

Some options have words separated by underscores. Added options with
same name and underscores replaced by hyphens.
