Actually, I was looking at the source because of this (Lib/traceback.py),
and it finds the line from the file by using the linecache module.

So
import linecache
print linecache.getline(filename, lineno) 
should work.

This module looks in the module path, and checks if files have changed since
last accessed. Oddly enough, I can't get it to show the changed file until I
actually let it show an exception, so I haven't found out everything yet.
But showing the file as it was when the module was compiled is what you want
anyway :)
