Bug: org-agenda-file-regexp not used in org.el?

[Wanrong Lin <wanrong.lin@gmail.com>]

Hi,

I am trying to customize the org-agenda-file-regexp variable to exclude 
those auto backup files starting with "#", but found out the regexp does 
not have any effect on agend file list. And I further found out it seems 
the variable org-agenda-file-regexp is not used in org.el at all. In 
function "org-agenda-files", the regular expression is hard coded to 
"\\.org\\'", as in these two lines:

(if (file-directory-p f)
     (directory-files f t "\\.org\\'")

I wonder whether this is a bug and should be fixed. Thank you.
