Bugs

1. XSpec commands which aren't recorded in the save file.

   The xspec abundan and xspec xsect commands are not recorded in the save file. If a fit is saved and then restored, the fit and statistics appear to be completely different.

2. xspec abundan always returns a status of 0.

   Executing xspec abundan by means of sherpa_eval returns 0 even when given an incorrect argument. For example, the following commands work (i.e. return 0 on success and -1 on failure):

   sherpa> sherpa_eval( "xspec abundan angr" )
       Abundances set to Anders & Grevesse
   0
   sherpa> sherpa_eval( "xspec abundan" )
   -1
   

   However the following do not recognize a failure:

   sherpa> sherpa_eval( "xspec abundan file foo" )
   Failed to open requested file with abundances
   0
   sherpa> sherpa_eval( "xspec abundan X" )
    'X' does not match.
     Choose from the following ABUND options (currently 'file'):
