Hi!

I think a found a bug in org-babel-tangle-file. It closes an user-opened
buffer if called with a symlink that points to the same file. Please see
the attached patch, which fixes the problem for me.

Subject: [PATCH] Fix bug in org-babel-tangle-file with symlinked files

Assume that there is file A and symlink B that points to file A. If
there is an open buffer that points to A and we
call (org-babel-tangle-file "B"), then this function kills the buffer
since get-file-buffer does not follow symlinks.
