I *guess* the primitive TeX behavior not to hyphenate the first word of a paragraph 
is the cause of the problem, and according to the LaTeX Companion this can be 
overcome by starting with \hspace{0pt}; either by 

    \index{VeryVery...@\hspace{0pt}VeryVery...}

or by a general hack of a macro invoked by \printindex (start printing each entry
with \hspace{0pt}).

Curious:
