SF bug #760703: SocketHandler and LogRecord don't work well together
SF bug #757821: logging module docs
Applied Vinay Sajip's patch with a few minor fixups and a NEWS item.
Patched __init__.py - added new function
makeLogRecord (for bug report 760703).
Patched handlers.py - updated some docstrings and
deleted some old commented-out code.
Patched test_logging.py to make use of makeLogRecord.
Patched liblogging.tex to fill documentation gaps (both
760703 and bug 757821).
