ERL-1432: Reverse search Bug

[OTP-Maintainer]

Original reporter: JIRAUSER16900
Affected version: OTP-23
Component: Not Specified
Migrated from: https://bugs.erlang.org/browse/ERL-1432

---

Recently Upgraded erlang from version OTP 20.3 to OTP 23.

When I the search function (Ctrl + r ) on the Eshell, then press backspace, the search will keep append the previous text every time the backspace is pressed.

This didn't occur in OTP 20.3

OS: debian 10

example:

1> ftp
(search)`': ftp
"press backspace"
(search)`': ftpftp

I have a fix for this and will be included together with other shell improvements
