Since 84e6fb9 (status: give more information during rebase -i,
2015-07-06), git status during an interactive rebase will show the list
of commands that are done and yet to be done. It implemented its own
hand-rolled parser in order to achieve this.
Now that we are able to fully parse interactive rebase's todo lists with
rebase_todo_list_parse(), use it in wt-status.c to reduce the amount of
code needed to implement this feature.

This patch is just an illustration, and is not quite right as it does not strip
comments and blank lines like the original did.
