One would think so, yes. However due to other things that TOVSolver
does, this change does not affect any current parfile (that produces
correct result, ie does not read uninitialized data).
TOVSolver contains a parameter TOV_Clear_Initial_Data which defaults
to yes and which sets all of gxx,gxy,gxz,gyy,gyz,gzz,k*,
betax,betay,betaz,alp, rho,eps,vel to zero (not Minkowski). This is
where currently shift=0 for TOVsolver is generated. This will still
happen after the commit. The only difference is in betax_p etc. which
were not initialized before (and had to rely on carpet's
fill_three_timelevels or mol's initial_data_is_crap).
With this patch betax is set to zero twice.
So: this is a bugfix towards the failure of tov_slowsector that you
observed. The bugs there go deeper (since the hydro initial data is so
convoluted) and this is only partial fix.
