This patch makes the git prompt (when enabled) show if a merge or a
rebase is unfinished. It also detects if a bisect is being done as
well as detached checkouts.
An uncompleted git-am cannot be distinguised from a rebase (the
non-interactive version). Instead of having an even longer prompt
we simply ignore that and hope the power users that use git-am knows
the difference.
