    FIXME/cagney/2001-01-18: The logic is backwards.  It should be asking if the
    target can single step.  If not, then implement single step using breakpoints.
   
-   A return value of 1 means that the software_single_step breakpoints
-   were inserted; 0 means they were not.  Multiple breakpoints may be
-   inserted for some instructions such as conditional branch.  However,
-   each implementation must always evaluate the condition and only put
-   the breakpoint at the branch destination if the condition is true, so
-   that we ensure forward progress when stepping past a conditional
-   branch to self. */
