comment-dwim and indentation

[Dan Nicolaescu]

comment-dwim is great, it has one wrinkle though: it places the
comments in column 0. So if one comments out a region in a C function
and then reindents the function, all the comments will be indented. 

Wouldn't it be better if comment-dwim would try to put comments at the
right indentation level so that reindenting would become an nop? 
(I don't know how feasible this would be, but asking doesn't hurt :-)
