[Rd] [External] parse data wrong for R 4.0. raw strings

[iuke-tier@ey m@iii@g oii uiow@@edu]

Looks like a bug. Will have a look when I get a chance.

Simpler version:

getParseData(parse(text = 'r"-|hello|-"'))


> getParseData(parse(text = 'r"(hello)"'))
   line1 col1 line2 col2 id parent     token terminal    text
1     1    1     1   10  1      3 STR_CONST     TRUE "hello)
3     1    1     1   10  3      0      expr    FALSE

The opening quote probably should not be there either.

More likely to get fixed sooner if someone can provide a patch.

Best,

luke
