Test cases for this (and other shell-command functionality) would also
be appreciated.

FTR, Tramp ignores this variable completely. Once it is fixed in
shell-command, we might want to fix it also for Tramp.

The current implementation in simple.el uses
shell-command--save-pos-or-erase and shell-command--set-point-after-cmd,
both are internal functions. Could we make them first class citizens,
that Tramp could profit from?
