It appears so, yes.

The function `comment-indent-default' does return comment-column, so
wisi-comment-indent should as well.

I never use 'comment-indent'; I just let 'align' deal with this; that
adapts better to the code at hand.

When I try this with the comment "-- some comment", the leading '-' is
put in column 55; the right end is at column 70. I think 70 is the
default for some fill function?
