function arguments downcased in help buffers

[Dan Nicolaescu]

emacs -Q 
C-h f defun RET

which CVS HEAD shows this:


defun is a special form in `C source code'.

(defun name arglist [docstring] body...)

Define name as a function.
The definition is (lambda arglist [docstring] body...).
See also the function `interactive'.

In 22.2 and older version from CVS HEAD used to show this:

defun is a special form in `C source code'.

(defun NAME ARGLIST [DOCSTRING] BODY...)

Define NAME as a function.
The definition is (lambda ARGLIST [DOCSTRING] BODY...).
See also the function `interactive'.


not sure why this happens, but it does not seem like a good idea, the
upper case used for arguments is quite helpful when trying to spot what
a certain argument does.
