Err...  It's a copy identical above one page above.  You want the same
comments that it got?  (i.e., none :-)

Should I perhaps add a comment before expand_main_function().  How
about this, as a separate patch?

/* Add any code we may have to add to the main() function.  Such
   instructions should be added before NOTE_INSN_FUNCTION_BEG, such
   that we don't emit additional line number notes for them, otherwise
   GDB would not regard these bits as part of the function prologue.
