A nice default value for the `destfile` argument in download.file() would
be `basename(url)` i.e. the name of the downloaded file. This would
correspond to default behavior in many other web/ftp clients and makes code
slightly more concise:
download.file("https://svn.r-project.org/R/trunk/doc/CRAN_mirrors.csv")
mirrors <- read.csv("CRAN_mirrors.csv")
default destfile in download.file()

This contradicts our approach not to overwrite files in the user filespace that are not explicitly mentioned as an argument. Best, Uwe Ligges
