Re: Debugging SMIE for sh-script.el

[Nikolay Kudryavtsev]

It returns 6, because when one of the smie-indent-functions returns nil, 
it does not mean that the line won't be indented, it just means that 
this function in particular(sh-smie--indent-continuation) could not 
indent the line and maybe there's another function further down the 
chain which can, smie-indent-exps that is and that's where 6 comes from.
