Issue #20052 has been updated by rubyFeedback (robert heiler).
Interesting. It seems to do some additional buffering? If it behaves differently to
readline then this may be a bug in behaviour; at the least if it is not a bug then the
user may want to be able to get the readline-behaviour and perhaps an option to toggle
between these two (though I think the Readline behaviour makes more sense, so I assume
this may be a bug indeed.)

Looks line reline behaves oddly with redirect (non tty)
With `ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]` and `Readline`:
```
$ echo 'foo' | ruby -e 'require "readline"; puts
Readline.readline(">")' > bar.log ; cat bar.log
foo
foo
```
With `ruby 3.3.0dev (2023-12-09 master 1cbe114d1c) [x86_64-linux]` and `Reline`:
```
$ echo 'foo' | ruby -e 'require "reline"; puts
Reline.readline(">")' > bar.log ; cat bar.log
>>f>f>fo>fo>foo>foofoo
```
