Wrong indentation for multi-line string templates

[lucaswerkmeister]

Input:

void testIssue39() {
    print("Text `` "with template" ``
               that starts indented");
}

Output:

void testIssue39() {
    print("Text `` "with template" ``
                                   that starts indented");
}

The second line doesn’t even need to be indented. It’s just always aligned to the ``` of the string part it’s currently in, not the"` of the proper string start.

String templates can be nested, by the way:

void testIssue39() {
    print("This `` "
                    text `` "
                             has" ``" ``
           nested `` "
                      templates" ``");
    // but is printed without any indentation
}

Luckily, the grammar has different token types for string starts, mids, ends, and literals, so it should be possible to keep some stack of charPositionInLines.

Crud, even more problems. The (’s indentAfter can only start after the string is completely processed.

Oohh… I not only need to carry over the charPositionInLines for write’s sourceColumn, but also the targetColumn, which currently comes from the countingWriter.

YES! It works! Commit incoming, but YES!! Sorry, I’m excited, this bug had me really worried. Carry on.

Somehow, this problem vanished, because I’m not dealing with it specifically… I’m okay with that :)
