issue with filling sectioning commands and adding nodes

[Patrice Dumas]

Hello,

I have an issue when filling gaps in sectioning.  For now, for example if
there is 

 @chapter chap

 @subsection subsec

The result is

 @chapter chap

 @unnumbered @asis{}

 @subsection subsec

That allows to have something that is not too invasive, in general the result
is something empty.

Now when one want to add nodes automatically (or not automatically) it is
not very good, because it is not obvious what node name should be used.

Maybe the simplest would be to use a number, which would lead to something 
along

 @chapter chap
 @node chap

 @unnumbered @asis{}
 @node 1

 @subsection subsec
 @node subsec

Does this seems right?  Any other idea?


Currently the result is just wrong

 @chapter chap
 @node chap

 @unnumbered @asis{}
 
 @subsection subsec
 @node subsec
