When parse():ing R code from *file* with a unclosed string, that is, a
string that has an open quoation mark, but not a ending one, the string
seems to be closed automagically. Is this a "bug"?
> code <- "x <- '123";
> parse(text=code) # Gives an error as expected
Error in parse(file, n, text, prompt) : parse error
> cat(file="foo.R", code)
> expr <- parse("foo.R") # Closes the open string
expression(x <- "123\n")
Parsing from stdin(), that is parse(), gives an error too.
