`org-attach-file-list' doesn't allow dotfiles

[Oleh]

Hi all,

I recently investigated why `org-open-at-point` uses smplayer to
open *.mp4 links, although the system's default is vlc.
The solution was to create ~/.mailcap with

    video/mp4; vlc %s

I wanted to store this file as an attachment in an org document, so I
don't forget about it, but this attachment can't be opened due
to `org-attach-file-list` ignoring all files that start with a dot.

I would modify it like this to ignore just "." and "..":

    --- a/lisp/org-attach.el
    +++ b/lisp/org-attach.el
    @@ -425,7 +425,7 @@ This can be used after files have been added
externally."
       "Return a list of files in the attachment directory.
     This ignores files starting with a \".\", and files ending in \"~\"."
       (delq nil
    -       (mapcar (lambda (x) (if (string-match "^\\." x) nil x))
    +       (mapcar (lambda (x) (if (string-match "^\\.\\.?$" x) nil x))
                    (directory-files dir nil "[^~]\\'"))))

Is there a reason behind this dot file restriction? Would anything break
if the proposed change was made?

regards,
Oleh

I'm copying John to this email, to see if there is any reason why
files starting with a dot cannot be attached.

Otherwise the change looks okay to me.

No reason I can think of.

I pushed a slightly different change:

I cannot think of any and John seems too busy right now.
Let's continue with this change and see if anything breaks.
