which-func, imenu, AUCTeX

[Greg Bognar]

Hi, this is (mainly) a cosmetic question.

I like to display the section (chapter, etc.) name on the modeline by using
which-func.  If I understand correctly, which-func uses imenu to get the
function (section, etc.) names, and AUCTeX supports imenu by setting
`imenu-create-index-function' to `LaTeX-imenu-create-index-function'.

However, the menu entry that is returned on the modeline looks like:

section{My Section}

or

chapter{My Chapter}

rather than

My Section

or

My Chapter

as I would expect (and as which-func does in other modes).  Worse, if in the
preamble I have something like

\titlespacing\section{0pt}{2\bigskipamount}{\parskip}

then I get "section{0pt}".

Is there a way to modify `LaTeX-imenu-create-index-function' (if that's indeed
the culprit) so that it only returns the section (chapter, etc.) name without
the \-less section (chapter, etc.) command?  And that it does not pick up things
like \titlespacing\section{0pt}?

(Interestingly, the items that appear in the imenu menu on the menubar are
slightly different than the items that are displayed on the modeline.)

Thanks!

All the best,
Greg
