pyenv-init.
- It turns out that the code I wrote was very similar to what was
already present in rbenv-init.
As rbenv is referenced when I am writing a pull request, I am assuming
that maintainers want code similar to what's already there.
WARNING:
The code will now not validate whether the specified shell is valid or
not, and if you make a silly mistake like writing `--parh` instead of
`--path`, the shell may be set to `--parh` and so forth. But I guess
this is acceptable.
