Fixes #279 using the suggestion from @hemanth, with some minor tweaks: - I kept the leading . because I figured there was a reason it was put there originally. - Changed the show_cursor method that's called when the process exits (prematurely or naturally) to be show_cursor_and_cleanup, and added a line to it that cleans up the tmp file.
