TAR_OPTIONS="-v" breaks install_github()

[dseynaev]

This works:

Sys.setenv("TAR_OPTIONS" = "")
remotes::install_github("klutometis/roxygen")

this does not:

Sys.setenv("TAR_OPTIONS" = "-v")
remotes::install_github("klutometis/roxygen")

I get the following output:

klutometis-roxygen-c42a2f0/
klutometis-roxygen-c42a2f0/.Rbuildignore
klutometis-roxygen-c42a2f0/.gitattributes
klutometis-roxygen-c42a2f0/.gitignore
klutometis-roxygen-c42a2f0/.travis.yml
[...]
klutometis-roxygen-c42a2f0/vignettes/roxygen2.Rmd
Error: Does not appear to be an R package (no DESCRIPTION)

I'm on Ubuntu 18.04.1 LTS, R 3.5.1 and remotes 2.0.2.9000

The issue is that -v does different things in tar's extract and in list modes. In extract mode it prints the files as they are processed, but in list mode it produces output similar to ls.

Sys.setenv("TAR_OPTIONS" = "-v")
utils::untar(Sys.glob("roxygen2_*"))

remotes uses untar() in both of these ways, so you cannot use -v as an option with remotes.
