It looks like M-g is already reserved as a prefix. In version 22.0.50 M-g
g runs 'goto-line. Try putting this in *scratch* and evaluating it. (C-j
after close paren of the form):

(global-set-key "\C-cg" ('goto-line)

I think that C-c is a mapping reserved for user bindings. That way you
won't have to mess with the default bindings into which a lot of thought
has gone. If C-c g is okay with you, you can put it in your .emacs.

oops!
 (global-set-key "\C-cg" 'goto-line)
rather.

That should be a space, otherwise you're trying to bind the "meta-g" key,
which I'm pretty sure you don't have on your keyboard.

If you're going to use ASCII art as a pointer, mae sure you're using a 
fixed-width font.  Your arrow is pointing to the quote before goto-line, 
not the hyphen in meta-g.

Er, normal email doesn't include font information, so it's your job to
make sure the font your use for reading mail is correct, not the message
sender's (and indeed, Stefan's message displays correctly if you use a
fixed-width font to read it).

err, he did. Looks fine on my fixed width *reader*. Sounds like you
are not using fixed width font.

LOL.

Well, the sender _and_ the reader have to use a fixed font, otherwise it
won't work as expected ( or they have to use the _same_ font ).
I get the arrow pointing to the 't' in meta, not pointing to the '-'.
I tried several fixed fonts. The problem is the 'tab' used by Stefan.

Actually Stefan didn't use a tab, the original poster did (Stefan just
quoted his text verbatim) -- but still it should cause no problems
unless your mail reader uses a non-standard tab width.

I agree.

No, it uses 8. The problem is the combination of a character (in this
example a space) and a tab. That combo produces a tab which is only 7 chars
long (because the space is also taken into account).

I hate tabs.

Why is there a problem?  Stefan's (space-only) text took that effect into
account, so in his post things line up perfectly.

Of course in the _followups_ to Stefan's post, which quote the whole
mess, things aren't lined up correctly (because the extra quotation
prefix shifts his space-space only text, but not the preceeding
tab-using text) ... but that's presumably not what Barry was complaining
about.

To be honest I don't know what Barry was complaining about, unless it's
perhaps "This damn MUA uses non-fixed-width fonts!"  That's a complaint
I also have with e.g. gmail, but surely the answer is "fix the MUA."

I'm using MT-Newswatcher, and I have it set to display in a fixed-width 
font (Monaco 10).

I've figured out the problem.  It displays TAB as a single space, rather 
than indenting to a tab stop.  I had no idea that the single line of 
code was indented with a tab rather than a space -- I had to cut and 
paste from MT-NW to Emacs to see this.

I *am* using a fixed-width font.

Another common problem with ASCII art is the use of TABs, since the 
sender and reader may not be using the same TAB width.

Sorry all for not realizing that the code I excerpted was using a TAB.

Oops! Yes I did misplace one hyphen between 'meta' and 'g'.
After removing it now it works.

Thank you all.

I use 

(define-key global-map (kbd "M-g") 'goto-line)

and works fine in emacs 21.4 (which comes bundled with slackware 10)
and emacs 22.0.50.1 (from CVS). I don't know if this is a specific
problem with emacs 21.3 but I doubt it. 

Maybe you should try starting with emacs -q and try executing the
above expression within the scratch buffer. Does this work?

Hope this helps,
