repl: internal repl's autocomplete is disruptive without inspector #40635

Version

v16.13.0 (and possibly others)

Platform

Linux foo 5.4.0-58-generic 64~18.04.1-Ubuntu SMP Wed Dec 9 17:11:11 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Subsystem

repl

What steps will reproduce the bug?

Compile node with --without-inspector, then start up the internal repl:

$ node
Welcome to Node.js v16.13.0.
Type ".help" for more information.
> const r = 10;
undefined

Now type r and press enter in the repl to have the repl display the value of r. You will find it instead forces the autocompletion of r to re and thus gives (the expected):

Uncaught ReferenceError: re is not defined

Pressing space after r and then enter in the repl causes the autocomplete to no longer complete and correctly shows the value of r.

How often does it reproduce? Is there a required condition?

Every time.

What is the expected behavior?

For the repl to not be disruptive when node is compiled with --without-inspector.

What do you see instead?
