Details:

This shouldn't work, right?


function blarg
  x = 1;
  y = 2;
  if x > y sldkfjdskljfskldklsdjf (x>y)
    fprintf('yup\n');
  else
    fprintf('nope\n');
  endif
endfunction


But it does this:


>> blarg
nope


The parentheses in the condition following the bogus keyword are significant.
If you remove them, you get a syntax error, like I'd expect.

Happens in 4.2, 4.4.1, and 5.1.0.
