----------------
Thinking about this some more, I think the FormatTokenLexer already does too
much. Maybe just use a regular lexer?
const SourceManager& SourceMgr = Env->getSourceManager();
Lexer Lex(Env->getFileID(), SourceMgr.getBuffer(Env->getFileID()), SourceMgr,
getFormattingLangOpts(Style));
Token Tok;
int MinInsertOffset = Code.size();
while (Lex.LexFromRawLexer(&Tok)) {
if (Tok.isNot(tok::comment)) {
MinInsertOffset = SourceMgr.getFileOffset(Tok.getLocation());
break;
}
}
