Add `merge.squash` about unison HOT 4 OPEN

Could you link to the deleted transcript for merge.squash.old if you think there's a chance we'll want to resurrect it after adding this

Hmm has that been deleted? I still use that as per Arya's recommendation last week #5099 (comment)

The latter would need to support

@me/app/branch> merge.squash @x/foo/jun_17 lib.x_foo_jun_17

unless there's a replacement workflow for you.
