Yes, at least theoretically. I don't think anybody has gone down
the path of investigating these effects.

The trouble with this is that you are checking on egrep which will give
you a positive for egrep versions >= 2.6.x, but the fix to texi2dvi might
have made that irrelevant. How about

     try
        texi2dvi
     except
        do Seb's thrice-repeated pdflatex (or whatever) call        

After everybody has updated to the latest texinfo, the exception code
can be taken out.

Alternatively, the texi2dvi method can be reverted: it was an idea that
was worth trying, but it has caused more harm than good at this point
- maybe it can be revisited in six months.
