[Python-checkins] python/dist/src/Doc/lib libdis.tex,1.39,1.40

Update of /cvsroot/python/python/dist/src/Doc/lib
In directory usw-pr-cvs1:/tmp/cvs-serv24418/Doc/lib

Modified Files:
	libdis.tex 
Log Message:
Further SET_LINENO reomval fixes.  See comments in patch #587933.

Use a slightly different strategy to determine when not to call the line 
trace function.  This removes the need for the RETURN_NONE opcode, so
that's gone again.  Update docs and comments to match.

Thanks to Neal and Armin!

Also add a test suite.  This should have come with the original patch...

- Returns \constant{None} to the caller of the function.  This opcode is
- generated as the last opcode of every function and only then, for
