[texhax] A different hyperref question

[Michael Barr]

I finally discovered that adding the option dvipdfm to hyperref resulted 
in losing the underlines on the links as I wanted.  But it caused a new 
set of errors that did not, however, appear to have any effect on the 
output, either the dvi or pdf:
Package hyperref Warning: Token not allowed in a PDFDocEncoded string,
(hyperref)                removing `math shift' on input line 1193.

What was on the lines 1193 and 2135 were section headers that had math in 
them.  These warnings did not appear until I added the dvipdfm option.
