Thank you very much for your quick and valuable answer.

Well, I found out that substituting '<<<' patterns with '^%<<<' (see attached
patch) makes the "hang" problem disappear, and I got the nested manual
folds to work as I wanted, although with the following caveats:

- A) To avoid that a comment fold "eats up" any subsequent manual folds
  separated by empty lines, like in the following situation...

    % Comment block
    % ...
    % End comment block
    
    %<<< Manual fold
    ...
    %>>>

  ...you must include the empty line (i.e. the '^$' pattern) in the comment
  folds endpattern (as I've done in my patch).  Note that this problem affects
  also your proposed patch.

- B) If you want things to work nicely in the preamble too, you have to switch
  off the 'preamble' value from g:Tex_FoldedMisc (e.g. setting it to
  'item,<<<,comments'), otherwise folds inside the preamble won't work anymore
  (you can only choose between a completely folded preamble or a completely
  unfolded one).

  Although this is not a major limitation (since you can always enclose the
  whole preamble in a big manual fold and retain nested manual folds), I tried
  to fix it by adding startskip and endskip pattern for the "preamble" folds,
  but without success (it seems that whatever skip pattern I add, the preamble
  doesn't get folded anymore, but I admit that I didn't play too much with
  that).

I tried your patch and it works nicely, it does not suffer from the "preamble"
bug as mine, although it suffers from the "empty line" bug I mentioned above.

I tried fiddling with it a bit in order to see if we can avoid to use two
different kinds of manual folding markers ("{{{" and "<<<"), but I couldn't
achieve any better results than those of my patch.

So, for now I'm quite satisfied with my patch, but I admit it could be
interesting to work on the B) problem, in order to restore "normal" preamble
folding working...

Thanks again for your reply!
