* if indentation is non-obvious, return a list of possible indentations
  and choose the first unless the current is one of the possible choices.

* ignore warnings in C-x ` ????

* improve the run-sml to allow running on another machine and to take args

* allow zero-indent after single-line `if a then b else'.

* allow right-aligning "and" with its correspondant.

* sample problematic indentations:
