guix shell readline issue with R

[Kyle Andrews]

Dear Guix,

When I run `guix install r` and then start an R process I get a 
readline-enabled REPL where I can abort commands with C-c C-c while keeping the 
process alive afterwards. When I run R from `guix shell r -- R` I don't get any 
readline support in R. Pressing C-c immediately aborts the process. This is 
inconvenient for interactive exploration. Is there a way to make guix shell 
work the same way as if the R command was installed into a profile?

Thanks for your help,
Kyle
