PS1, Line 7: Make -r/-w/-v argument optional
It seems they are not fully optional, they are only optional when `-i` parameter is provided? Maybe it's better to say "optional with -i parameter provided", something like that.

However, the critical important place where it should be explained is not the commit message, but the manpage, you need to update doc/classic_cli_manpage.rst to fully explain the usage.

In this case, also very useful would be to give examples (full command line examples) of a valid usages with this feature.
