Move cursor to the beginning of the line before erasing #126

Closed HarryMichal closed 2 years ago

The \033[K escape sequence signifies 'clear from cursor position to the end of the line'. Without moving the cursor to the beggining of the line first it results in no text being deleted. The behaviour of Carriage Return (\r) in terminal emulators is not formally standardized but it is generally interpreted as a move to the beginning of the line.

Tested on both Linux and Windows (cmd.exe, WSL2 and Windows Terminal).
