[O] require blank line in TeX output of org (and/or how to use the LaTeX package linguex via org-mode)

[Benjamin Slade]

I want to be able to use the LaTeX package "linguex" in org-based beamer
presentations. But this package requires a special syntax where after
the environment there must be a blank line in the LaTeX source (!=a blank line
in the LaTeX output). How do I do this in org-mode?
