Documentation
String that starts block comments, or nil if such don't exist.
Block comments are ended by c-block-comment-ender, which is assumed
to be set if this is. At least one of c-line-comment-starter and
this one is assumed to be set.
Note that it's currently not enough to set this to support a new comment style. Other stuff like the syntax table must also be set up properly.
