title: How to display m[,n] lines around current line in pdb?
body: <p>The Python 2.7 debugger <code>pdb</code> allows to display lines <code>o</code> to <code>p</code> with <code>l [o[,p]]</code>, but one has to figure out which line the debugger stand on and then substract and add. Is there a way to display an <code>m</code> lines before and <code>n</code> lines after the current line without arithmetics?</p>
