You could use (\n|.) to match any character including newlines
(regex(6) says that a new line is not cosidered "any character", and
as a matter of fact, \n is part of the sam language, not of regex
itself). However, since the longest possible regex will be matched,
then you will also match the end of the comment, so for example in:
/* comment 1 */
bar
/* comment 2 */
you will match everything, I don't think that is what you want.

Edit ,x/\/\*/.,/\*\//c/COMMENT/

The possibility of modifying the dot is powerful. Many times it is
much easier than finding an huge regex.
