AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.

These files are a subset of the python-2.7.2.tgz distribution from python.org.  Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

+"""Word completion for GNU readline 2.0.
+
+This requires the latest extension to the readline module. The completer
+completes keywords, built-ins and globals in a selectable namespace (which
+defaults to __main__); when completing NAME.NAME..., it evaluates (!) the
+expression up to the last dot and completes its attributes.
+
+It's very cool to do "import sys" type "sys.", hit the
+completion key (twice), and see the list of names defined by the
+sys module!
+
+Tip: to use the tab key as the completion key, call
+
+    readline.parse_and_bind("tab: complete")
+
+Notes:
+
+- Exceptions raised by the completer function are *ignored* (and
+generally cause the completion to fail).  This is a feature -- since
+readline sets the tty device in raw (or cbreak) mode, printing a
+traceback wouldn't work well without some complicated hoopla to save,
+reset and restore the tty state.
+
+- The evaluation of the NAME.NAME... form may cause arbitrary
+application defined code to be executed if an object with a
+__getattr__ hook is found.  Since it is the responsibility of the
+application (or the user) to enable this feature, I consider this an
+acceptable risk.  More complicated expressions (e.g. function calls or
+indexing operations) are *not* evaluated.
+
+- GNU readline is also used by the built-in functions input() and
+raw_input(), and thus these also benefit/suffer from the completer
+features.  Clearly an interactive application can benefit by
+specifying its own completer function and using raw_input() for all
+its input.
+
+- When the original stdin is not a tty device, GNU readline is never
+used, and this module (and the readline module) are silently inactive.
