That looks wrong to me; in sed, to use a pattern delimiter other than / *as
an address* you need to start it with a backslash so it knows it's a
pattern delimiter coming up and not a command without an address. That is,

    :foo:p

is an illegal command, but

    \:foo:p

uses : as the delimiter for an address pattern. This does not apply to the
"s" command, since it knows after the "s" verb that a pattern follows.

(Note that ":" is a valid sed command, although not widely used; it's a
label for a branch instruction. You just gave it a rather odd-looking
label, and the reinplace does nothing as a result.)
