You escaped one address delimiter too many. man sed:
Try your sed command again, with the second | unescaped.
To avoid commenting out an already commented line, you can either add the # to all matching lines, and then remove duplicates, or extend the address, like
Using a similar address for the reverse operation, including 0 - n spaces in the s command, is left as an execise for the reader.
Thank you very much.

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
