[Rd] strange behaviour in R 2.0.0 (PR#7275)

[Fan]

Dear Prof Ripley,

After looking at my original C code, which is different in 2.0.0
should be (sorry, not tested as I've desinstalled 2.0.0,
tired of the time wasted):
 > a=list(x=1:2)
 > a$y = strptime(c("20010101","20020101"),"%Y%m%d")
 > a = data.frame(a)
 > rbind(a,a)

For the point 1 in PR#7269 (failure in installing packages from source),
I've encountered that for several packages (so "toto" means nothing).
I guess that should come from changes somewhere related to the "index"
check in the perl script for making process. I agree with you it'd be
difficult to claim that a bug, but anyway, it's not expected as
I've checkec the different files (man, INDEX, DESCRIPTION) and can't
figure out what's wrong, and it WORKS with 1.9.1.

ps: sorry for having posted 2 times (PR#7269, PR#7272), I've used
the Web interface of R-Bugs to send the report, and after posting
the first one, I've figured out that there was an error in the email
address (xiao.gang.fan at libertysurf.fr instead of xiao...1 at libertysurf.fr).
