sys.stdout is not what you want. You want to avoid creating temp file?
Then it's better to dump log into memory. You can't dump pure unicode to
stdout, do you? What about utf-8 instead? Ok?

So let's use StringIO Python standard library.

import codecs
from cStringIO import StringIO
import sys

import bzrlib
from bzrlib import log
from bzrlib.branch import Branch

# prepare utf-8 encoded stream
sio = codec.getwriter('utf-8')(StringIO())

# open branch
b = Branch.open('./myscripts/')

# print log to our stream
lf = log.LongLogFormatter(to_file=sio)
log.show_log(b, lf)

# get the log as utf-8 string
s = sio.getvalue()

# and then we can close our stream
sio.close()

Then you can use utf-8 data in s as you wish. You can print it to stdout:

sys.stdout.write(s)

or do something else.
