 at the end

In GNU Emacs 30.0.50 (build 20, x86_64-pc-linux-gnu, GTK+ Version
 3.24.37, cairo version 1.17.8) of 2023-04-05 built on
 felix-lifebooka531
Repository revision: 8678708ad10b17a4609c950a02cf39ab9ff86317
Repository branch: makepkg
Windowing system distributor 'The X.Org Foundation', version 11.0.12301001
System Description: Arch Linux

Configured using:

 -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security

 LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now'

Configured features:

LCMS2 LIBSYSTEMD LIBXML2 MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER PNG
RSVG SECCOMP SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS TREE_SITTER WEBP
X11 XDBE XIM XINPUT2 XPM XWIDGETS GTK3 ZLIB

Important settings:
  value of $LANG: de_DE.UTF-8
  locale-coding-system: utf-8

If the cursor is in some line at a column position that is lower than
the length of the prompt (e.g. ELISP> in ielm) and comint-clear-buffer
is used, the cursor ends up inside the prompt. This has been tested with
gdb and ielm on emacs 3.0.50 started with 'emacs -Q'

Thanks!

Is having a (move-end-f-line nil) in comint-clear-buffer wise?

What are the other use-cases of comint-clear-buffer? It
makes sense for IELM or Terminal buffers, but we need to
identify other use-cases of this, before we push a fix.
