[Python-checkins] CVS: python/dist/src/Doc/lib libdis.tex,1.21,1.22

[Thomas Wouters]

Update of /cvsroot/python/python/dist/src/Doc/lib
In directory slayer.i.sourceforge.net:/tmp/cvs-serv24798/Doc/lib

Modified Files:
	libdis.tex 
Log Message:

Apply SF patch #101135, adding 'import module as m' and 'from module import
name as n'. By doing some twists and turns, "as" is not a reserved word.

There is a slight change in semantics for 'from module import name' (it will
now honour the 'global' keyword) but only in cases that are explicitly
undocumented.
