bug: Emacs does not see buffer changes for .tex files which are below symlinks

[gasche]

My system has directory a that is in fact a symlink to b. If I edit a/foo.tex using Emacs, texpresso does not see the updates unless I use M-x texpresso-signal explicitly. Editing b/foo.tex works as expected.

(I have not tested what happens if foo.tex itself is a symlink.)
