What happens if the `<` is immediately after an escaped newline? Eg:
```
... \
<foo>
```
I *think* we use the location of the `\` as the `DDTok.Offset` in this case.
Worth adding a testcase. If it fails, this would be the fix:
```suggestion
const char *DDTokPtr = SkipEscapedNewLines(BufferStart + DDTok.Offset);
if (ParsingFilename && *DDTokPtr == '<') {
```
