How I found the bug: LaTeX previews were not displayed in Org mode
because the path where the file lies contains a symbolic link
(e.g. `/home/user/docs/org' directory where `/home/user/docs' is a
symbolic link to a directory).
Bug description: `file-relative-name' (in `files.el') doesn't take into
account symbolic links.
How to reproduce:
1. Run `mkdir -p ~/a_dir/org'.
2. Run `ln -s ~/a_dir/org ~/docs'.
3. Run `emacs -Q ~/docs/example.org'.
4. Insert into the file "$2+2=4$", press `C-c C-x C-l', and see that it
does not work.
5. Kill emacs.
6. Run `emacs -Q ~/a_dir/org/example.org'.
7. Insert into the file "$2+2=4$, press `C-c C-x C-l', and see LaTeX
preview.

This is not a bug. If you want to resolve symlinks in a file name,
use file-truename before calling file-relative-name. The latter is
purely a syntactic function which merely analyzes its file name
argument, and should not hit the disk.

I'm therefore closing this bug report.
