[9fans] cursor editor

[Kenji]

Hello 9fans!

I have written a mouse cursor editor.
Please use if you need it.

If the following string "8^[$@B=^[(J" (eight half) is not recognized on your Plan9
terminal, you must amend winit() in this program or get correct
program from:
plan9.aichi-u.ac.jp/cedit.l

This is a subproduct for my another project:
I would like to have a grab program that enables to cut a screen.
