Incorrect Unicode BOM generation

Description

py-YAML 3.07, with Python 2.5 and FreeBSD (package name py25-yaml-3.07_2)

When yaml.dump() generates stream in utf-16be or utf-16le, it generates byte-order mark (BOM), but makes it incorrectly. Example:

>>> yaml.dump("xyz", encoding = 'utf-16be')
'\x00\xff\x00\xfe\x00x\x00y\x00z\x00\n\x00.\x00.\x00.\x00\n'

Instead, it should generate:

'\xfe\xff\x00x\x00y\x00z\x00\n\x00.\x00.\x00.\x00\n'

P.S. I guess it also should generate BOMs for utf-32*

Thank you for the report and the fix. Fixed in [351].

UTF-32 is not supported by the YAML specification.
