Details:

Take `5.^2` and insert spaces between `5` and `.`, between `.` and `^`, and
between `^` and `2`. The possible bug is that expressions 3 and 4 do not give
errors though they separate `.^` into `. ^`. Can someone verify?

```

octave:1> 5.^2
ans = 25
octave:2> 5.^ 2
ans = 25
octave:3> 5. ^2
ans = 25
octave:4> 5. ^ 2
ans = 25
octave:5> 5 .^2
ans = 25
octave:6> 5 .^ 2
ans = 25
octave:7> 5 . ^2
error: parse error:

  syntax error

>>> 5 . ^2
        ^
octave:7> 5 . ^ 2
error: parse error:

  syntax error

>>> 5 . ^ 2
        ^

```
