three bugs fixed

- notes
bug in edit/ triggers in immutable but not master branch
bug triggered by changes to layer 059: we're finding an unspecialized call to 'length' in 'append_6'

hard to debug because trace isn't complete
just bring out the big hammer: use a new log file

length_2 from recipes.mu is not being deleted (bug #1)
so reload doesn't switch length to length_2 when variant_already_exists (bug #2)
so we end up saving in Recipe for a primitive ordinal
so no valid specialization is found for 'length' (bug #3)

why doesn't it trigger in a non-interactive scenario?
argh, wasn't checking for an empty line at end. ok, confidence restored.
