I've just searched the web for that.  Ruby has block comment delimiters
=begin and =end.

It would be possible to handle these in syntax.c, but somewhat clumsy
and awkward.

Presumably ruby-mode handles these with syntax-table text properties
applied to the = sign and the terminating d, which is a little clumsy,
but not too bad, at the Lisp level.
