* Properly reset formatting at the end of question prompts Currently, the second prompt for the delete command uses a bold + red format mode using escape codes. However, this mode is not reset at the end and ends up leaking unto next lines on the terminal. This change will make sure all `question` strings passed to the `Prompt` function will be closed properly by a reset escape sequence. Includes a fmt change too. * chore: fix code usage comment --------- Co-authored-by: Abiola Ibrahim <git@abiosoft.com>
