On my system, the following raises an error when evalled with CVS
emacs -Q:

(apropos-command (quote ("vc")) 1)


Backtrace:

Debugger entered--Lisp error: (void-function vc-previous-version)
  documentation(vc-previous-version t)
  apropos-command(("vc") 1)
  call-interactively(apropos-command nil nil)


There are actually two problems related to this bug:

(1) In vc-hooks.el, there is a definition

(define-obsolete-function-alias
 'vc-previous-version 'vc-previous-revision "23.1"),

but the function `vc-previous-revision' is not defined.

(2) `apropos-command' should handle errors caused by broken function
aliases. Else, cases like (1) make `apropos-command' partly unusable.

 of 2008-08-29 on green

            * vc-hooks.el (vc-previous-version): Move alias to vc.el.
            * vc.el (vc-default-previous-version): Move alias here
            * from vc-hooks, and fix name typos.  (Bug#856)
