Follow-up Comment #14, bug #55968 (project octave):

> And though you can symbolically utilize sinc in MATLAB as shown above, you
can't in Octave:

This is fixed in git now:

>> syms q
>> sinc (q)
ans = (sym) sinc(π⋅q)

Here, again, you can see that calling 'sinc' on a symbolic variable uses the
normalized sinc to be consistent with numeric Octave and Matlab, but SymPy
only knows how to print it with respect to its own unnormalized 'sinc'
