How do I open a file for edit from the command line under Windows?

How do I open a file for `edit` from the command line under Windows?

Mainly I am looking to open the file in the default editor associated for it (not to be confused with default action for this filetype).

This is different than just "executing" the file, so `start filename` is not a solution.

Note: this would require to use ShellExecute in one way or another.

Update: I added `Python` as an alternative to `batch`.

Here is a sample Python script that opens a file for edit, if there is an editor assigned to its filetype.

import os
from ctypes import c_int, WINFUNCTYPE, windll
from ctypes.wintypes import HWND, LPCSTR, UINT
prototype = WINFUNCTYPE(c_int, HWND, LPCSTR, LPCSTR, UINT)
paramflags = (1, "hwnd", 0), (1, "text", "Hi"), (1, "caption", None), (1, "flags", 0)
MessageBox = prototype(("MessageBoxA", windll.user32), paramflags)

filename = "readme.txt"
os.startfile(filename, "edit")

try:
os.startfile(filename, "edit")
except WindowsError, e:
MessageBox(text=str(e))

64 bit Windows does not support edit command.
