Yes. So, if CQL_HISTORY is empty string or not set at all, use default
destination. If it is set to something else, write it there. If it is
/dev/null, do not try to create directories leading to that file.
edit: I am not sure how save_history treats /dev/null, if it errors out or
what. That is interesting corner case. Have you already tested yet?

> User on GH sent:
> I just started using cassandra and found that it creates history folder in my
> home directory. I personally don't like it and all my folders follow XDG
> standard. I found stackoverflow question related to it which says that it's
> not possible to do without configuring source code of cqlsh.py.
> In this pull request I added a feature to choose history directory using
> environment variable. The name of variable is CQL_HISTORY. Why ? Because
> postgres and node-repl use approximately the same convention
> (NODE_REPL_HISTORY,PSQL_HISTORY). If you want I can change the name.
