Update of /cvsroot/python/python/nondist/peps
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv16944

Modified Files:
	pep-0000.txt pep-0315.txt 
Log Message:
Pick-up responsibility for PEP 315 (per agreement with Isaac Carroll).

Correct the semantics for continue statements found in the do suite.
The previous semantics did not match that for do-while statements in
other languages.

-    A continue statement in the do-while loop will behave somewhat
-    differently than in the standard while loop.  Instead of jumping
-    back to the loop condition, it will jump to the beginning of the
-    first suite of the loop.  This is to ensure that the setup code
-    has a chance to do its job before the condition is evaluated.
