[R] New versions of lattice and grid

[Paul Murrell]

Hi

grid_0.7-4 has been submitted to CRAN.
Apologies for the stuff up.
I may try to go on holiday now ... :)

Paul

technical note:  I used is.expression() rather than is.language()
because that is all that grid's C code checks for.  Yes, this should be
expanded to allow is.language() at some point.

even more technical note:  is.language() does not correspond to the
C-level function isLanguage ...
