C-c C-f in octave-mode of emacs 22.1 normally inserts something like
this:
function B = hasWon (X, z, z0)
## usage: B = hasWon (X, z, z0)
##
##
endfunction
Now it inserts:
function B = hasWon (X, z, z0)
## usage: B = hasWon (X, z, z0)
##
##
endfunction
i.e. it has wrong initial indentation. This might be a flaw of smie.

Indeed. There were several bugs triggered here.
I installed the patch below which fixes this problem.

Thank you for the fix. However with this change: prog-indent-sexp with
point on the first letter of 'function' gives me this funny indentation
and extra whitespace:
function A = dox (n)
## usage: A = dox (n)
##
##
endfunction

Duh, thanks. I've installed the additional patch below which should fix
it right this time.

Found an infinite loop.
In a new octave-mode buffer, insert "function" and make sure there is no
trailing newline. Now move to point-min and M-x forward-sexp to enter
infinite loop.
