[tex-k] [bug] minus sign in MetaPost labels disappears withdvips(k) 5.90a

The minus sign is at 0 of cmsy10, and this 0 is shifted to 161 by -G1
for the minus sign in the TeX source. But dvips cannot change \000 in
the eps to \241.
Please do not use the "obsolete" -G1 option. In the next release
of teTeX, -G1 option is disabled in config.pdf.
