The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every
file, since the individual files are not individually distributed except
as part of the entire package.
Previously, we were only destroying sockets on end if their readable
side had already been ended. This causes a problem for non-readable
streams, since we don't expect to ever see an 'end' event from those.
Treat the lack of a 'readable' flag the same as if it was an ended
readable stream.
Fix#4751
With -e or --eval, require() can load module using relative path.
node -e 'require("./foo")'
But it can't load module from node_modules directory.
node -e 'require("foo")'
Fixes#1196.
