gh-122237: Fix REPL wrong auto-indentation with comments

• Issue: REPL auto-indentation is wrong with comments #122237

At this point, it will never auto-indent if there is only a comment without other code in the last line. This will produce the following situation, and I am trying to fix that if possible.

At this point, it will never auto-indent if there is only a comment without other code in the last line. This will produce the following situation, and I am trying to fix that if possible.

For what it’s worth, I’m not sure I would consider this a bug. Presumably, the user had to un-indent the comment line deliberately, so I would expect the following line to also be un-indented, if that makes sense.

Are there other situations where this behavior leads to incorrect indentation?

This is fixed already.
