Subject: inline() doesn't consider pi as a built-in constant

Bug report for Octave 3.0.1 configured for i486-pc-linux-gnu

Description:
-----------

  * inline() doesn't consider "pi" as built-in constant.
    When looking for unbound variables during the construction
    of the anonymous function, inline() will include "pi" in the
    arguments list, while it will ignore "i" and "j".

    Maybe this behavior is intentional, but it differs from MATLAB's
    inline() which ignores "pi" when constructing the arguments list.

Repeat-By:
---------

octave:1> f = inline('sin(pi*x)')
f =

f(pi, x) = sin(pi*x)
