#1187: Cactus allows for negative error level

     Type:  enhancement  |      Status:  new                
 Priority:  minor        |   Milestone:                     
Component:  Cactus       |     Version:  development version

-------------------------+--------------------------------------------------
 Currently, Cactus allows to set a negative error level through the command
 line option. This leads to CCTK_WARN(0,"") not necessarily aborting. While
 this is not wrong by itself, a lot of code assumes an abort at that point.

 I propose to change CCTKi_SetErrorLevel() to only accept non-negative
 error levels and to change the command-parsing code to give an error
 message for that case as well. Patch is attached.
