Attached you will find the patch I applied to the debian package which
fixes this behaviour. I set ft=3Dtex if just one '%' is found since many
third part classes (e.g. LNCS, ENTCS) starts in such a way.

Of course the patch is now for /usr/share/vim/vim63/filetype.vim.

Bram, could you please consider including the attached patch to future
vim versions?

Many thanks.
Cheers.
