Hello Stefan,
Some user from the Octave community has noticed the following change:
x = 12; # abc abc abc abc abc abc abc abc abc
# abc abc abc
If you TAB in the second comment line, that line will be moved to column
0.
I tested the example in emacs 22.1 and the second comment is supposed to
be aligned to a certain column (similar to ; and ;; in lisp-mode). Will
you be able to bend smie to do this? Thanks.
Leo

matlab.el also does the comment alignment well. Stefan, do you think
this is possible to do with smie?

Of course. In the very worst case you can change (buffer-locally)
smie-indent-functions to add any ad-hoc rule.
But maybe this can be fixed globally in smie-indent-comment.

Thanks for the comment (did I just use a pun?).
Unfortunately I have little knowledge of smie so I have to rely on
others to get this to behave. Thanks in advance.

No, no, you don't. smie-indent-functions is just a hook that runs
functions that come up with some indentation choice. It basically sits
between line-indent-function and smie proper. You can add your own
function which will not itself need to use anything from smie.
Look at its docstring.
