Subject: Add built-in string variables 'quit' and 'exit' that display a hint on
X-Git-Tag: v1.5.2a1~95
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d89fa0c5761254c970af72e5abcea420fd23e893;p=python

Add built-in string variables 'quit' and 'exit' that display a hint on
how to exit (in a platform dependent way!).  We use os.sep to
determine which platform we're on, since I expect that this will work
better for minority platforms.
