- Makes Ranger plugin use the standard `$ZLUA_LUAEXE` and `$ZLUA_SCRIPT`
environment variables that `z.lua` itself uses.
- Better error handling; errors loading plugin no longer cause
`ranger` to quit entirely.
- Briefly document the plugin
`.zlua` file doesn't get created for Powershell users that use [Starship Prompt](https://starship.rs/) and place z.lua init command before starship init command in their `profile.ps1`.
Couldn't reproduce the bug in zsh. Didn't test other shells.
Most notably, this adds instructions of changing $_Z_CD. I think many
`fish` users would find them useful.
See https://github.com/skywind3000/z.lua/pull/131 for more background.
This makes the installation instructions more conventional (`|source`
instead of `psub`). This also deletes the second (equivalent) set of instructions.
If the warning in that sentence is important, we could add it back, but
it would apply to all the shells, wouldn't it?
Finally, some wording is improved.
I don't know if the default of `builtin cd` is a good one, as opposed to simple `cd`. It took me quite a bit of debugging before I figured out why, on my `fish` shell, changing directories with `z.lua` messed up the `cdh` (cd history) command.
I think the best thing would be to change the default. However, if you have a good reason to stick with it, I thought that documenting this potentially unexpected behavior might help.
