$ keeps the selections a shell command exits 0 on, and line end is gl

$ was a second key for line end, which helix never meant: in helix it is
shell_keep_pipe. It now arms the pipe prompt with a $ marker, runs the
command once per range with that range's text on stdin, and keeps the ranges
it exits 0 on; the primary stays if kept, else the last kept range takes
over, and keeping none changes nothing. The runner's answer is all or
nothing, so the command runs in a subshell whose status is echoed as its
output. Line end stays on helix's own gl and End; the snapshots, tutor and
docs that pressed $ for it press gl.
