* objcopy.c (copy_object): If the output file format is `binary',
and the start address was not set using --set-start, default the
start address to zero. This hack is because the `binary' output
file format uses the start address to set the virtual address of
the first byte in the file.
* binutils.texi, objcopy.1: Add some notes on generating S-records
and binary files.
