link bug

["Eddward DeVilla" <eddward@gmail.com>]

Hi,

    I'm not on the latest version yet and it will be a few day until I
can get there.  However, I found a bug in 4.51 when trying to store a
link using C-c C-l.  I believe that's org-insert-link.  In any case
org-insert-link gets called in there somewhere and dies calling
(file-truename buffer-file-name) to determine if the link is in the
same file as the org buffer.  This is invalid when the buffer doesn't
have a file behind it.   There needs to be a check to make sure
buffer-file-name is not nil.  (Or org has to not allow file-less
buffers).  The reason for the file-less buffer was that I've started
creating small outlines with links when I want to throw together a
quick code review.

I'm not sure what the right answer is.  may you just skip the case if
there is not file behind the buffer since links into file-less buffer
would seem to be impossible.  On the other hand, You may want to allow
links back to the same buffer just in case the user decides to save it
to a file later.  For now, I'm going to hack mine by wrapping the "(if
(equal ..." inside an "(if (buffer-file-name) ..."
