<82bf24ce537ca9333d72c2b4698864817801f10f.1577933387.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.507.git.1577933387.gitgitgadget@gmail.com>
From: Heba Waly <heba.waly@gmail.com>

Display a hint to the user when attempting to delete a checked out branch saying "Checkout another branch before deleting this one: git checkout <branch_name>".

Currently the user gets an error message saying: "error: Cannot delete branch <branch_name> checked out at <path>". The hint will be displayed after the error message.
