Thanks for the thorough review, Eli!

OK, included:

  For convenience, @value{GDBN} comes with a program,
  @command{gdb-add-index}, which can be used to add the index to a
  symbol file.  It takes the symbol file as its only argument:

  @smallexample
  $ gdb-add-index symfile
  @end smallexample

  @xref{gdb-add-index}.

Done.

This refers to a section name, not a file name.  Should it still be
marked as @file?

Here's how I've rewritten this part:

  To determine whether a file contains such an index, use the command
  @kbd{readelf -S filename}: the index is stored in a section named
  @code{.gdb_index}.  The index file can only be produced on systems
  which use ELF binaries and DWARF debug information (i.e., sections
  named @code{.debug_*}).

Thanks!  I'll wait for your reply re. the @file question, and then push
it.
