Subject: [PATCH] Avoid justifying of 'in' prompt

This little diff is to avoid rjustify of the 'in' prompt, because in configurations with variable prompt size (e.g. my pysh prompt showing \w), going to a smaller prompt cause only-reversed-by-restart blank spaces addition in beggining of 'in' prompt. Right justify is ok to 'in2' and 'out' prompts, but very ugly and weird in 'in' prompt.
