Various performance boosts and code clarifications.

So, will this patch be applied?

Sorry, I don't see any value in this kind of patch.

The line "contline = += line"  is broken. The "+=" transformations and 
else-clause eliminations trivially re-arrange code without any real 
savings.  The "while 1" to "while True" transformation should not be 
done in Py2.x because the latter is much slower ("while True" requires 
loading a global variable and a test; in contrast, "while 1" is 
optimized to an unconditional jump.
