[AUCTeX] Nested snippets in preview-latex

[Wei-Ting Lin]

Hi there,

I really think this function would be very useful for editing long
equations.

I noticed that this hasn't been supported, but "... such nesting might be
achieved by rerunning preview-latex on the footnote contents when one opens
the footnote for editing. "

I'm wondering how this can be done.

Thank you,
Wei-Ting
