Now that "dosed" is going to be banned, what would people think of
"newins" (and the other "new*" commands) accepting "-" as the first
argument? I don't know how many usage cases there are, but the
following are obvious:

sed 's/quux/quuux/' foo | newins - foo

It would allow for here documents:

newins - bar <<-EOF
# configuration file (for example)
EOF

or even:

newins - baz <<<$'# a short
# file'
