[Rd] names lost in functions from packages installed by R-devel r74500

[Francois Rousset]

Dear list members,

If I install with R-devel r74500 on Windows (sessionInfo below) the 
attached 'bugdemo' package with the single function

foo <- function() {
   named <- c("bar"=TRUE)
   print(named)
   return(named)
}

then run

 > bugdemo::foo()
[1] TRUE
[1] TRUE

The "bar" name is lost. It is not lost when I define foo in the R 
session instead of using its packaged version.

To reproduce:

=======================================

install.packages("bugdemo_0.1.1.tar.gz",type="source",repos=NULL)

bugdemo::foo()

=======================================

I also tested whether this was a problem with the "R CMD build" step or 
the "install.packages()" step by building with R 3.4.4 and installing 
with R-devel, and reciprocally, and the problem appears to be in the 
install step of R-devel.
