Yes, thanks. Some minor wording tweaks, which make it easier for me to 
understand:

Trap execution flow and hand over control to GDB. The Emacs source file 
src/.gdbinit uses this via the GDB command "break Fdebugger trap".

This function has no effect.  It is reserved for debugging, and is not 
called by Emacs otherwise.
