[pdftex] Increasing grouping levels

[Fabrice Gadaud]

		Hi,

	I got this error message in various logs:
		
	"TeX capacity exceeded, sorry [grouping levels=255]"

	I got something similar, earlier, about nested_levels. I successfully
changed texmf.cnf and everything went fine. But I don't know how to
setup groupings_level the same way, despite searching the web. Any
attempt to increase various variables did not solve this problem.
