[Python-Dev] cpython: Remove some extraneous parentheses and swap the comparison order to

I appear to be in the minority here, but this particular example does
not strike me as egregiously unreadable.  To the contrary, by bringing
the constant to the front, this form saves me from having to read to
the end of the line.  The same mental economy appears when constants
are brought to the front of chained if-elif cases in Python:

if 'a' == typecode:
  ..
elif 'b' == typecode:
  ..

is slightly more readable than the more traditional alternative.
Probably because I can mentally ignore the "== typecode" part and see
the switch structure more clearly.

Either way, I don't see a big issue here and I would keep "len == 0"
intact even if I reordered typecode == 'u' as Brett did.  The only
consistency that I would enforce is to use the same order in the
chained if-elif cases, but otherwise this should be left to the
discretion of the author.
