In today's CRAN snapshot, there turned out to be 198 packages that use
4.1 syntax in examples but not in code, 5 packages that use 4.2 syntax
in examples but 4.1 in the code, and 3 packages that use 4.2 syntax in
examples but not the code. This may be slightly imprecise because I
don't have some of the Rd macro packages installed and run
Rd2ex(stages=NULL) on manually-parsed Rd files without installing the
packages.

Attaching a patch that checks the syntax used in Rd examples at the
same time as the main R code, not necessarily the best way to perform
this check. Is it perhaps worth separating R/* checks from man/*.Rd
checks? Should R CMD check try to reuse the Rd database from the
installed copy of the package?
