   MID_STATEMENT is nonzero if the PC is not at the beginning of that

   The current symtab and line is updated to reflect S and LINE.

   Return true if the annotation was printed and the current symtab and

   source file for S can't be found, or LINE is out of range.

   This does leave GDB in the weird situation where, even when annotations
   are on, we only sometimes print the annotation, and only sometimes
   update the current symtab and line.  However, this particular annotation
   has behaved this way for some time, and front ends that still use
   annotations now depend on this behaviour.  */
