[Rd] Making R CMD nicer

[Jason Xu]

In my humble personal opinion, I try to avoid bash scripts longer than a
couple lines because I find the syntax so obtuse and unintuitive it's
difficult to maintain and write less buggy code. But that is mostly a
reflection of my personal inexperience.
I think the only time a bash script is really needed is for maximum
portability in systems _with bash_.
(I would use python for a wrapper in personal projects, given python comes
pre-installed on many linux systems and OS X, but I completely understand
not wanting to burden Windows users with an extra python dependency to
install.)
