Assembler -aL Command-line Option

[Tracy Kuhrt <Tracy dot Kuhrt at microchip dot com>]

When specifying a --help command-line option for the assembler, the -aL
option is listed.

  -a[sub-option...]       turn on listings
                          Sub-options [default hls]:
                          c      omit false conditionals
                          d      omit debugging directives
                          h      include high-level source
                          l      include assembly
                          m      include macro expansions
                          n      omit forms processing
                          s      include symbols
                          L      include line debug statistics (if
applicable)
                          =FILE  list to FILE (must be last sub-option)

However, when trying to use the -aL command-line option, I receive the
following error:
Assembler messages:
Fatal error: invalid listing option `L'

I am using binutils version 2.11.  Should the -aL option be removed from
the show_usage function?  Or should a flag be set in the parse_args
function?
