[Idle-dev] IDLE's save-before-run requirement

[Wesley Chun]

the subject of this message is basically to get some feedback on
having to save a script within IDLE before running it.  when i'm
making a good number of small changes to my file, doing separate
sets of keystrokes started to get old, so i hacked together a
small patch that allows you to "save-n-run."

i thought i'd get Guido's opinion b4submitting a PEP.  he suggested
i also get some more comments from here.  below is basically what i
proposed and his response.

please direct any comments to me (and/or the group).  thanks!
