Sure.

I am not quite sure I understand what the issue is.

Octave mode has never provided syntax support for single quoted strings
because there is no way (short of actually parsing the code) of telling
these apart from single quotes used for transposition.

The comment style provided by Octave mode is the same as for Lisp mode,
so a single comment char is aligned at the comment column.
