  Tip: Try `view 7` to see the source of any numbered item in the above list.

  I added 0 definitions to the top of /home/unison/code/unison/nimbus-structured-interrupts.u                          

  You can edit them there, then run `update` to replace the definitions currently in this
  namespace.

If I do the same with edit.new (which is actually the old edit???) it works fine:

@cloud/nimbus/structured-interruption> edit.new 1-7
@cloud/nimbus/structured-interruption> edit.new handleIncomingConnection handleIncomingRequest handleIncomingWsForkRequest handleServiceHttpRequest README toWS updateAll

  ☝️

  I added 7 definitions to the top of /home/unison/code/unison/nimbus-structured-interrupts.u

  You can edit them there, then run `update` to replace the definitions currently in this
  namespace.

Environment (please complete the following information):

• ucm --version 5f3f532ce

Oops I think that this was user error. I didn't realize that edit no longer adds definitions to the scratch file if they are already there.
