Great, thanks for testing.

You could be right, but I couldn't find any callers of that function,
so it was hard for me to reason about that specific case.  Stefan,
since you introduced tex-cmd-doc-view into tex-mode.el, could you take
a look and tell whether using display-tex-shell-buffer-action in its
default value there makes sense?  If not, what would be a better
default?
