Please find attached the patch.

Actually, I'm noticing `LaTeX-insert-label' overlaps with
`LaTeX-label-alist' (which is undocumented in the AUCTeX manual) and
`LaTeX-section-label'.  The problem is that when RefTeX is used,
`reftex-label' ignores `LaTeX-label-alist' and `LaTeX-section-label',
instead `LaTeX-insert-label' is valuated before calling
`reftex-label'.

We could completely remove the new `LaTeX-insert-label' and check with
`LaTeX-label-alist' and `LaTeX-section-label' whether a label should
be inserted, before calling `reftex-label'.  What do you think?

Bye,
Mosè
