- explain seekable
- when seekable==1, test fp.tell() and set it to 0 if that fails
- support overridable method iscomment(line) to weed out comments
- check for unread() method on file object before trying to seek

And one of my own:

- Add a get() method which behaves like a dictionary's get(); this is
actually implemented by giving getheader() an optional second argument
to specify the default, and aliasing get to getheader.

including the new __stdin__, __stdout__ and __stderr__.
Also moved setttrace around to its proper place in the alphabet.

(all with index entries!).  Also update the list of functions that
take or yield a time represented as a 9-tuple.

level of a form.  This means that browsers that omit the content-type
header when sending a POST command aren't penalized so heavily.

The 1.5.1 tabnanny.py suffers an assert error if fed a script whose last
line is both indented and lacks a newline:

if 1:
    print 'oh fudge' # no newline here:

The attached version repairs that.

the type names), make sure that numeric objects are considered smaller
than all other objects, by forcing their name to "".

and lists; if the size is negative, raise an exception.  Also raise an
exception when an undefined type is found -- all this to increase the
chance that garbage input causes an exception instead of a core dump.

not in restricted mode.

__dict__ can be set to any dictionary; the cl_getattr, cl_setattr and
cl_delattr slots are refreshed.

__name__ can be set to any string.

__bases__ can be set to to a tuple of classes, provided they are not
subclasses of the class whose attribute is being assigned.

__getattr__, __setattr__ and __delattr__ can be set to anything, or
deleted; the appropriate slot (cl_getattr, cl_setattr, cl_delattr) is
refreshed.

(Note: __name__ really doesn't need to be a special attribute, but
that would be more work.)

Slightly more featureful than regexdemo.py.

and list the host name when prompting for the password.

the median-of-three code to get a few percent back.

but it can no longer raise an exception when called by several threads
simultaneously.

doesn't work of course.

Also replaced random()*32000 with randint(0, 31999).

else the damn thing won't compile on Windows :-(

_getch(), _getche().

Fix bogus error return when open_osfhandle() doesn't have the right
argument list.

Tkinter.  This adds a separate lock -- read the comments.  (This was
also needed for Mark Hammond's attempts to make PythonWin
Tkinter-friendly.)

The changes have affected the EventHook slightly, too; and I've done
some more cleanup of the code that deals with the different versions
of Tcl_CreateFileHandler().
