emacs --help , improvement for output formatting

[Dilyan Palauzov <Dilyan.Palauzov@aegee.org>]

    Dear Developers,

    When I type `emacs --help` with emacs 22.1.1, the first  2 
paragraphs are:

Run Emacs, the extensible, customizable, self-documenting real-time
display editor.  The recommended way to start Emacs for normal editing
is with no options at all.

Run M-x info RET m emacs RET m emacs invocation RET inside Emacs to
read the main documentation for these command-line arguments.


and the last 3:

You can generally also specify long option names with a single -; for
example, -batch as well as --batch.  You can use any unambiguous
abbreviation for a --option.

Various environment variables and window system resources also affect
Emacs' operation.  See the main documentation.

Report bugs to bug-gnu-emacs@gnu.org.  First, please see the Bugs
section of the Emacs manual or the file BUGS.

The point is, that they are truncated within emacs and do not use the 
whole width of the terminal. In my opinion it must be the terminal who 
decides when this lines are to be truncated.

But, if you can get the line width from emacs at the --help stage, then 
you could also improve the output for --color, that --help prints:

--color, --color=MODE           override color mode for character terminals;
                                  MODE defaults to `auto', and can also
                                  be `never', `auto', `always',
                                  or a mode name like `ansi8'

Here the last 3 lines shall exand to the end of the terminal, not be 
truncated much before.

    Със здраве,
       Дилян
