I don't have your inputrc to verify, of course, but I will note that:

The readline variable assignment syntax doesn't include `='; it's just
`set variable value'.

`tilde' is misspelled.

These are not readline variables; they're bindable command names.

It's likely that these have been problems for a long time; the code to
warn about unknown variable names is new in readline-7.0. It came into
the devel branch in January, 2016.

You can't link bash-4.4 against any readline version except 7.0; there will
be undefined symbols because bash-4.4 takes advantage of new readline

You're right, I haven't released a readline patch yet.  That comes next.
