Bug 299836

Let's say I type this ("|" shows the text cursor):

def foo():
    a=2
    def bar():
        b=4
        c=b|

and move the cursor to the beginning of the line:

def foo():
    a=2
    def bar():
        b=4
        |c=b

If I delete one indentation level by backspacing four spaces:

def foo():
    a=2
    def bar():
        b=4
    |c=b

the code is not reparsed, and 'b' is still highlighted as a known variable, thinking the 'c' assignment is still inside the 'bar' function. Typing *anything* other than a space will trigger a reparse and make 'b' in the last line get highlighted as an unknown variable (yellow underline).

Similarly, if I have this:

def foo():
    a=2
    def bar():
        b=4
        |

code completion shows 'a' and 'b' as known local variables. But if I delete one level of indentation and complete again, it still shows 'b' (even though it's not in scope), and typing or deleting anything will trigger a reparse and make completion become correct (not showing 'b').

Very strangely, if I unindent by pressing Shift-Space instead of deleting the four spaces, the code *is* reparsed immediately, and both highlighting and completion correctly reflect the scope change.
