[Orgmode] Export bug: LaTeX TOC headline numbers above 100 overlap headline

[Jeff Kowalczyk]

When the headline count for a pdftolatex export gets to be more than 100 lines, 
the TOC renders with the headline number directly touching the headline text. 
More than 1,000, and it starts to overlap.

It would seem that LaTeX calculates the space to allocate for the headline 
number based on too few initial entries.

I have included a simple test case below.

Thanks,
Jeff
