Summary: python-mode and nested indents

Initial Comment:
Using Python-mode 4.6 and GNU emacs 21.2.2, I enter the
following:

if x < 0:
    for i in range(100):
        print i
else:
    print "x is negative"

If I now put the cursor on the "else:" line and hit
tab, it erroneously changes the indentation to line the
"else" up with the "for" above it.

Frankly, I hadn't thought of that possibility!

However, I still consider the behavior a bug, for two
reasons:  (1) I can type something that's syntactically
valid, hit tab, and have it change the meaning of what I
typed, and (2) It changes the indentation in the same way if
I say "elif:" instead of "else:", even though that change is
not syntactically valid.  That is (using -> to indicate a
tab):

if x < 0:
->for i in range(100):
->->print i
elif x > 0:
->print x

Again, hitting tab on the "elif" line will indent the "elif"
to line up with the "for", even though the result is
syntactically invalid.

Andrew, why is that erroneous?  Loops in Python have 
(optional) "else:" clauses too.  There's no way for pymode to 
guess whether you intended the else to go with the if or the 
for.  I expect it looks backward for the closest-preceding 
construct the else-statement could "belong to", and finds 
the for-loop first.
