sed compat

[fisx]

On Linux, both variants have the same output, but on mac, allegedly only the second one works:

$ echo '{"email":"l8TVlbK0@example.com","locale":"en","accent_id":0,"picture":[],"name":"demo","id":"29740ea6-c54a-4a92-8fd5-3f8c5b05cdc3","assets":[]}' | sed 's/.*"id":"\([0-9a-z-]\+\)".*/\1/'
$ echo '{"email":"l8TVlbK0@example.com","locale":"en","accent_id":0,"picture":[],"name":"demo","id":"29740ea6-c54a-4a92-8fd5-3f8c5b05cdc3","assets":[]}' | sed 's/.*\"id\":\"\([a-z0-9-]*\)\".*/\1/'

See #712 (thanks @limengyu1990!)

I have a Mac and I approve this message.
