emacs -Q

Commands bound to keys are linked to help on them.

M-: (setq-default indent-tabs-mode nil)

C-h b

The listed commands are no longer linked. Clicking them with mouse-2
does nothing (error "No cross reference here").

I can reproduce this in GNU Emacs 22.1.1 (i686-pc-linux-gnu, GTK+
Version 2.10.6) of 2007-06-02 on escher and in GNU Emacs 22.1.50.6
(i686-pc-linux-gnu, GTK+ Version 2.10.6) of 2007-06-30 on escher.  In
both, however, there are two exceptions to the lost links: 
C-M-x           eval-defun
M-x             execute-extended-command

Likely a typo.  Does it work if you replace the line

		      (skip-chars-backward "^\t\n")

in `help-make-xrefs' with

		      (skip-chars-backward "^ \t\n")
