Update of /cvsroot/python/python/dist/src/Lib
In directory usw-pr-cvs1:/tmp/cvs-serv26665

Modified Files:
	pdb.py 
Log Message:
Fix SF bug 579701 (Fernando Pérez); an input line consisting of one or
more spaces only crashed pdb.

While I was at it, cleaned up some style nits (spaces between function
and parenthesis, and redundant parentheses in if statement).
