Original GitHub issue: https://github.com/asciinema/asciinema/issues/222

As mentioned here https://github.com/asciinema/asciinema/pull/196#issuecomment-288148352 the set of environment variables saved by asciinema rec in env map should be defined/controlled.

What could work is to have a white-list of env variables saved under env key in the recording header. It could default to SHELL,TERM and you could override it either via command line switch when recording or via config file option.

Having this, if you also want to save $USER, $HOSTNAME and $CUSTOM_STUFF you could set the white-list to for SHELL,TERM,USER,HOSTNAME,CUSTOM_STUFF and have all the information that's useful to you.
