Bug#892319: neovim: Neovim does not provide vim.basic alternative

[Edoardo Putti]

Package: neovim
Version: 0.2.2-3
Severity: normal

Dear Maintainer,

when using ldapvi or other packages that query the alternatives database
for vim.basic it spawns nano or other editors different from vim.

As an example you can use

ldapvi --host ldap.forumsys.com --user cn=read-only-admin,dc=example,dc=com --discover --bind-dialog always

as described by this page for their Online LDAP Test Server https://www.forumsys.com/tutorials/integration-how-to/ldap/online-ldap-test-server/ the password for read-only-admin is password

This is the result of succesfull authentication, ldapvi will show a page
with information about the LDAP entities using nano.

Upon exiting there will be a new line of message from
/usr/bin/sensible-editor.

--- Login

Filter or DN: cn=read-only-admin,dc=example,dc=com
    Password: ********
     23 entries read
/usr/bin/sensible-editor: 25: /usr/bin/sensible-editor: /usr/bin/vim.basic: not found
No changes.

I'm not aware of the differences between vim and vim.basic so I don't
know if vim.basic should still be used.

Should neovim provides vim.basic or, the other way round, packages
should not depend on this?
