In code like this:
def foo():
x = 1
# indentation is wrong after this comment
y = 1
the 'y = 1' line is not properly indented. (Hitting
tab in this line does not fix it either.)
It seems like the indentation engine should ignore
comments.
(In case this form messes up whitespace, the 'x = 1'
line is indented and the others are not.)
