regression bug with getParseData and/or parse in R-3.1.0
...With R-3.1.0 I get:
> getParseData(parse(text = "{1}", keep.source = TRUE))
line1 col1 line2 col2 id parent token terminal text
7 1 1 1 3 7 9 expr FALSE
1 1 1 1 1 1 7 '{' TRUE {
2 1 2 1 2 2 3 NUM_CONST TRUE 1
3 1 2 1 2 3 5 expr FALSE
4 1 3 1 3 4 7 '}' TRUE }
Which has two problems:
1) the parent of the first expression (id=7) should be 0
2) the parent of the expression with id=3 should be 7
For reference, with R-3.0.2:...

A bug understanding F relative to FALSE?
...'(' TRUE (
## 4 1 3 1 3 4 6 SYMBOL TRUE F

I would expect that token for F is the same as token for FALSE.
Thank you!

Mapping parse tree elements to tokens
I would like to map the parsed tokens obtained from utils::getParseData()
to the parse tree and elements obtained by base::parse().
It looks like back when this code was in the parser package the parse()
function annotated the elements in the tree with their id, which would
allow you to perform this mapping. However when the code was included in R
this functionality was removed.
