Yes, it is somewhat tricky to decide whether end is being used inside
an index expression.  What rule would you use (need not be stated in
Lisp)?  Once you've decided that, the fix is to either modify
octave-block-end-regexp appropriately, or, if the rule can't be stated
in a regexp, to replace occurrences of

 (looking-at octave-block-end-regexp)

with the function that can determine whether we are looking at the end
of a block and that is not confused by other uses of "end".

Yes, but can't the meaning be discerned from the fact that "end" used as
an index always has a round parentheses about it?  Parentheses around an
end wouldn't be valid when "end" means end of a loop or conditional.


It doesn't necessarily. I have used the following to extract the first and last elements from a vector:
Or, suppose you wanted to do a cylic shift of a vector:
So, there are a lot of exceptions you could cook up ...
