+Continuing evaluation after a breakpoint:\n\
+ If the \"-i false\" option is used, and execution is interrupted by a breakpoint hit, once\n\
+ you are done with your investigation, you can either remove the expression execution frames\n\
+ from the stack with \"thread return -x\" or if you are still interested in the expression result\n\
+ you can issue the \"continue\" command and the expression evaluation will complete and the\n\
+ expression result will be available using the \"thread.completed-expression\" key in the thread\n\
+ format.\n\
