[Rd] parse():ing a unclosed string
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"?
Example:
> 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
> print(expr)
expression(x <- "123\n")
Parsing from stdin(), that is parse(), gives an error too.

Re: [Rd] make check-all fails (PR#8063)
Please do read the docs: this test is randomm and will fail about 1 in 50
and if you have already run make check, you have already passed it.
Definitely no bug in R.

It's clearly intentional from the comments in the sources: EOF during
parsing is treated specially.
Generally the parser has not been written to find all syntactic errors: in
any case one would need a formal language definition to do that. Prior to
R-devel quite a few mal-formed constants were accepted, for example.

What exactly is in this file?

Those are _not_ the same thing. I am not clear what you actually tried,
as you cannot generate an EOF this way.

These are rather old for non-released versions: there have been many
changes since then (especially in R-devel).

Re: [Rd] documentation for eval() typo
Thank you. It would be easier to deal with thes reports if in future you could provide a patch against the source file (here eval.Rd).
