[Discuss-gnuradio] Bug in fmdet_cf_impl.cc

[Eugene Grayver]

There's an obvious bug in the very old fmdet_cf_impl.cc file.  I reported it before, but it has not been fixed.  Unfortunately I can't do a pull request, so somebody please fix it:

fmdet_cf_impl.cc:109

<<<Sdot = d_scl * (-S0+d_8*S1-d_8*S1+S4);

>>>Sdot = d_scl * (-S0+d_8*S1-d_8*S2+S4);

Note that the third term should be S2, not S1.  Otherwise, terms 2 and 3 just cancel each other.
