The change in 393255a leads to infinite recursion in repObj when ]save is called on a workspace with a train in an unscripted namespace

[dyaandys]

Mantis 14223 details that you get the message "generating a faulty script" when attempting to ]save a workspace which contains a train inside an unscripted namespace:
n←⎕ns''
n.t←'+',⊢
]save n /tmp/

With the change in 393255a the ]save now leads to infinite recursion in repObj:

⎕SE.SALT.NStoScript.repObj[35]*
.. a very large number of this line ..
⎕SE.SALT.NStoScript.repObj[35]
⎕SE.SALT.NStoScript.repObj[13]
⎕SE.SALT.NStoScript.ntgennscode[40]

⍎
[#] ⎕SE.input.c.SaltInSpice.Run[6]
⍎
⎕SE.SALTUtils.CallUserCode[0]
⎕SE.UCMD[2]

repObj[35] is
len<≢obj:P⍣rc⊢(⍕s),'⍴',0 ref ∇ obj⍴⍨len~1
