You are absolutely incorrect.

I just did it again, in `emacs -Q' in 22.3:

GNU Emacs 22.3.1 (i386-mingw-nt5.1.2600)
 of 2008-09-06 on SOFT-MJASON
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4)'

The result is, exactly as I stated:

;;   `abcdef'

Please do not reply that way, without even trying the recipe. It doesn't help.

Let me repeat the instructions differently, just so you are clear. Insert this
text at the beginning of *scratch*: "  `abcdef'". Follow that by hitting RET to
insert a newline.

Put point at bob and hit C-SPC to set mark. Use C-n to move past the inserted
line.

Do M-x comment-region

You will *NOT* see this in Emacs 22 (or 21 or 20 or ...):

  ;; `abcdef'

You WILL see this in Emacs 22:

;;   `abcdef'
