Thanks for the example.  In this case GSL_CONTINUE is an error code
which indicates that the iterate function could not make any
reasonable progress, although it didn't encounter any fatal errors
(therefore calling the function again is possible).  With the example
program this occurs when it's essentially at the minimum.  In
hindsight, GSL_ENOPROG would have been a better choice--I'll log that
as a bug and put a note in the manual.
