Error arguments in pl_exec.c

I get the following warnings in HEAD

pl_exec.c: In function ‘exec_stmt_raise’:
pl_exec.c:2538: warning: format not a string literal and no format arguments
pl_exec.c:2538: warning: format not a string literal and no format arguments


Attached patch seems right to me - objections?
