[R] Why Rscript behaves strangely with file name starting with 'size'?

[Allan Engelhardt]

It looks like a bug in R, not Rscript: what Rscript does is effectively

R --file=size.R


and you can easily test that

echo 'print("Hello world")'>  size.R
R --file=size.R


give you the error while

cp size.R asize.R
R --file=asize.R


works as expected.

None of which helps you directly, but perhaps one of the developeRs can 
help fix what seems to be broken options parsing in the R code.
