[PATCH] config doc: improve exit code listing

[Stefan Beller <sbeller@google.com>]

The possible reasons for exiting are now ordered by the exit code value.
While at it, rewrite the `can not write to the config file` to
`the config file cannot be written` to be grammatically correct and a
proper sentence.
