Subject: bug#43558: [PATCH]: Fix (forward-comment 1) when end delimiter is escaped.

Hello, Mattias.

Since forever, but only in the CC Mode test suite.  :-(

I just tried it out with gcc, and it seems that \*/ does indeed end a
block comment.  But an escaped newline doesn't end a line comment,
instead continuing it to the next line.  So I got confused.  Thanks for
pointing out the mistake.

It seems that as well as the existing variable
comment-end-can-be-escaped, we need a new one, say
line-comment-end-can-be-escaped, too.  In C and C++ modes, these would
be nil and t respectively.
