Unicode in GNUTranslations.  Also provide better descriptions of
*gettext() overridden methods, esp. w.r.t. the behavior in the face of
fallbacks.

    __init__(): Removed since we no longer need the coerce flag.
    Message ids and strings are now always coerced to Unicode, /if/
    the catalog specified a charset parameter.

    gettext(), ngettext(): Since the message strings are Unicodes in
    the catalog, coerce back to encoded 8-bit strings on return.

    ugettext(), ungettext(): Coerce the message ids to Unicode when
    there's no entry for the id in the catalog.

Minor code cleanups; use booleans where appropriate.

GNUTranslations constructor.

   use re module
   make chomp() use rstrip()

   use re module
   use .split() string method

Doesn't use 'for line in sys.stdin'; that ends up changing its interactive
behaviour.

Run these demo scripts through reindent.py to give them 4-space indents.  I've verified that their output is unchanged.

As a side issue on this bug, it was noted that list and tuple iterators
used macros to directly access containers and would not recognize
__getitem__ overrides.  If the method is overridden, the patch returns
a generic sequence iterator which calls the __getitem__ method; otherwise,
it returns a high custom iterator with direct access to container elements.

Closes SF bug #724751.

Theres now a separate function for each of the format codes
b, B, H, I, k, i, l, L, K.

definitions.

There's no separate documentation for this module yet - apart from the
doc-strings which explain the APIs.

Allows use of tuples for the initializer.

The additional code complexity and new NOP opcode were not worth it.

Also some typos and removed trailing whitespace on the lines.
