[Bug-gsl] documentation bug

[Bas Zoetekouw]

Hi!

There seems to be a small bug in the GSL documentation (version 1.4).
According to the documentation (section 31.7), the gsl_root_test_delta()
function is declared as:

   Function: int gsl_root_test_delta (double x1, double x0, double epsrel,
   double epsabs)

while gsl-1.4/roots/convergence.c says:

   int
   gsl_root_test_delta (double x1, double x0, double epsabs, double epsrel)

The third and fourth argument are switched in the documentation.

Hope this is helpful.
