Wrong vertical error ranges

[odersky]

minimized code

object Test {
  "abc"
    .foo

  "abc"
    .bar.baz

  "abc"
    .bar
    .baz
}

Output

-- [E008] Member Not Found Error: test.scala:2:2 -------------------------------
2 |  "abc"
  |  ^
  |  value foo is not a member of String - did you mean String("abc").+?
3 |    .foo
-- [E008] Member Not Found Error: test.scala:5:2 -------------------------------
5 |  "abc"
  |  ^
  |  value bar is not a member of String - did you mean String("abc").+?
-- [E008] Member Not Found Error: test.scala:8:2 -------------------------------
8 |  "abc"
  |  ^
  |  value bar is not a member of String - did you mean String("abc").+?
9 |    .bar
three errors found

The first and third error messages are as expected, but the second is not: it strips the interesting part, namely .bar from the output.

Comparing 2nd and 3rd error points to a possible cause: When displaying multi-line errors, it seems the last line is dropped unless it forms part of the error range in its entirety.

Expectation

The last line should never be dropped if it contains tokens. Ideally, if only a part of the last line forms part of the error range, that part should be indicated with horizontal markers. I.e. something like this:

5 |  "abc"
  |  ^
  |  value bar is not a member of String - did you mean String("abc").+?
     .bar.baz
     ^^^^
