- accept empty string from focus_get
- map coords() return value through getdouble and splitlist

- move compile() inside try-except
- add code so you can do "python pdb.py <script> <arg> ..." to debug <script>

(then f may be None).

- Better staggering of windows
- Windows have zoombox by default, and zooming works
- DrawControls->UpdateControls
- Better scrollbar show/hide

underscores.

"make libinstall" no longer implies "make sharedinstall".
"make altinstall" and "make altbininstall" install the python binary
with a version number, for tentative installations (this does not
install the include files or man page).

Forget about the trick to create directories through dependencies --
it's impossible to get it right in the light of parallellizing Make
implementations and the inability to specify dependencies between
directories (because creating the subdirectory modifies the parent).

directory containing argv[0] is inserted in front of sys.path.
If argv[0] contains no directory, an empty string is inserted.
If argv is empty, nothing happens.

Added maketrans(), a utility to create a translation table.

	arguments and explicit calls to .pack() are used; no more dictionaries
	are being passed to Tkinter constructors.  Otherwise, the example is
	unchanged.  (The app isn't implemented as a Python object.)

reliably distinguish binary files from text files (and Mac Netscape
sends all files in "binary" form, i.e. it sends text files with only
CR delimiters...).

blank lines.

keep_blank_values option to parse().

The optimizations consist mostly of using local variables to cache
methods or instance variables used a lot (e.g. "self.write").

The loopholes allows marshalling extension types as long as they have
a __class__ attribute (in which case they may support the rest of the
class piclking protocol as well).  This allows pickling MESS extension
types.
