Bug Report

Current Behavior
If a SyntaxError is thrown from @babel/parse, startLine is ignored (it uses the "real" start line).

Input Code

const { parse } = require("@babel/parser");

parse("5+", { startLine: 10 });

Expected behavior/code
It should take into account startLine.

Hey @tolmasky! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community that typically always has someone willing to help. You can sign-up here
for an invite.

This is particularly annoying, because as far as I can tell, it means I need to do string manipulation of the message because you can't get the message without the (line:column) portion.
