Licensing in source-map-support.js #343
Description
Line 286 of source-map-support.js indicates that the code that follows has been copied from V8, which is BSD-3-Clause-licensed (see e.g. their license file here and the original file the code seems to be copied from here - header also mentions the BSD license).
IMO the license & applicable copyright should be included in source-map-support to reflect this.
