I found a nasty drawback of this method. If that hbox is used, the first
paragraph is not evaluated correctly and considered as the second one. When
indentation is enabled, the first paragraph after the title is not usually
indented, but now it is. Additionaly, even if indenting is disabled, there is a
bigger distance between title and the following para.
\setupindenting[yes, 2em]
\starttext
\section{The first section}\index{the first section}
The first para.\par
The second para.
\section{The second section}\leftboundary\hbox{\index{the second section}}
The first para.\par
The second para.
\stoptext
I could eventually avoid inserting that 'index' tweak into titles, but this is
another exception which an end-user should keep in mind ..and.. I hate
exceptions ;-)
Any idea?
Thanks, Jan
