1. The first paragraph of a function's NSEdoc is used as a short
summary. Some of these were very long, so I split off a shorter summary.
2. Use asterisks (*) to denote bulletted lists, not 'o'
3. Wrap lines at 80 columns
4. a couple other spelling and formatting fixes
Windows uses UTF-16 little-endian. Since this is a common use case,
utility functions are provided such that this:
x = unicode.utf16to8(v)
is equivalent to this:
x = unicode.encode(unicode.decode(v, unicode.utf16_dec),
unicode.utf8_enc)
but faster (fewer intermediate tables)
