Trailing white space after a line continue character
(\) causes an "invalid token" error when parsing.

The trailing white space can be either tabs or spaces.

Tested against Python 2.0 and 2.1b1; error occurs in
both.

Request resolution: parser should ignore trailing white
space after line continue character

Sample code:

# ok -no trailing white space past line continue char
print	'case 1a' + \
	'case 1b'

# invalid token error - one space after line continue
char
print	'case 2a' + \ 
	'case 2b'

# invalid token error - one tab after line continue
char
print	'case 3a' + \	
	'case 3b'
