I have 21.4.13 set up on one box, and I'm setting up 21.4.13 on another
box, and copying over elements of the "init.el" from the first box.
One annoyance I've had for a long time in shell mode is that ^c while
running an app in shell mode does not kill the app. I've tried to find
a solution to this for a long time, to no avail. I've just gotten used
to it.
When I set up 21.4.13 on this new box, I got to a point where I realized
that ^c was killing the app. This was nice to see.
However, now I see that apps that produce somewhat long-running output
are only producing blocks of output, only when I move the cursor. On
the old laptop (where ^c doesn't work), the output comes out normally.
Are these two issues related? I'm not sure which problem is more
annoying. Is there something I can do to fix the "blocky output"
problem?

Because C-c is a universal prefix, it takes 2 C-c's (that's C-c C-c)
to kill a process in shell-mode.
C-h k C-c C-c reports:
C-c C-c runs `comint-interrupt-subjob'
`comint-interrupt-subjob' is an interactive compiled Lisp function
-- loaded from "comint"
(comint-interrupt-subjob)
Documentation:
Interrupt the current subjob.

maybe. there's lots of black magic out there you need to do when
working with tty's and ^c, and it varies from system to system. if your
two boxes have different os's or different linux installations or maybe
even different versions of the same installation, they might have
different config flags.
are you compiling yourself? if so, check the config.h files that were
produced; do a diff on the files from your two boxes and see if there's
anything different, esp. in the following settings:
/* Many flavors of PTY support */
#undef HAVE_GETPT /* glibc's easy pty allocation function */
#undef HAVE__GETPTY /* SGI's easy pty allocation function */
#undef HAVE_OPENPTY /* BSD's easy pty allocation function */
#undef HAVE_GRANTPT /* Unix98 */
#undef HAVE_UNLOCKPT /* Unix98 */
#undef HAVE_PTSNAME /* Unix98 */
#undef HAVE_KILLPG /* BSD */
#undef HAVE_TCGETPGRP /* Posix 1 */
#undef HAVE_ISASTREAM /* SysV streams */
#undef HAVE_SYS_PTY_H /* AIX */
#undef HAVE_SYS_PTYIO_H /* HP-UX */
#undef HAVE_PTY_H /* Linux, Tru64 */
#undef HAVE_LIBUTIL_H /* BSD openpty */
#undef HAVE_UTIL_H /* NetBSD openpty */
#undef HAVE_STROPTS_H /* SysV streams */
#undef HAVE_STRTIO_H /* SysV streams TIOCSIGNAL */
#undef HAVE_TERMIOS
#undef HAVE_TERMIO
#undef NO_TERMIO
#undef SIGNALS_VIA_CHARACTERS

it might be a misconfiguration of one of the above values (or maybe some
other value). does it happen on 21.4.18 too?
