branch --list: print useful info whilst interactive rebasing a detached HEAD
When rebasing interactively (rebase -i), "git branch --list" prints a line indicating the current branch being rebased. This works well when the interactive rebase is initiated when a local branch is checked out. This doesn't play well when the rebase is initiated on a detached HEAD. When "git branch --list" tries to print information related to the interactive rebase in this case it tries to print the name of a branch using an uninitialized variable and thus tries to print a "null pointer string". As a consequence, it does not provide useful information while also inducing undefined behaviour. So, print the point from which the rebase was started when interactive rebasing a detached HEAD.
