It is currently stated that calling `ArgumentParser.error()` exits with a code of 2. However, it is not explicitly stated that this method is used in `ArgumentParser.parse_args()` when the arguments are invalid. Adding a note about the exit code to the `exit_on_error` argument of the `ArgumentParser` constructor makes this relationship explicit, and also makes this piece of information easier to notice.

@savannahostrowski, this may be related to one of your recent changes. I am not sure that it is worth to repeat "print sys.stderr" here, but we should not create a new ambiguity. |

For consistency's sake, it's probably worth having the same phrasing here as well. |
