Re: Debugging SMIE for sh-script.el

[Nikolay Kudryavtsev]

SMIE funcalls smie-indent-functions until one of them returns non-nil. 
If we do smie-config-show-intent on your line we get:

Rules used: :list-intro "" -> nil

This means that our line has been indented by the default logic of 
smie-indent-exps. If we go through it we'll see that it's trying to 
align with the first arg of sexp which it thinks is "/bar". So in effect 
it's treating your expression as if it was:

({foo} /bar

           --baz \ --quux)

P. S. Incidentally I've spent like the entire last week writing SMIE 
indentation logic for some proprietary language with a really terrible 
syntax, and I'm not even close to getting it done, so that's how I know 
this stuff.
