Is the sequence

	// a co\
	mment

a legal comment in ANSI C++?  ANSI C's translation phases are as follows:

	1.  Trigraphs are replaced by non-trigraph equivalents.
	2.  backslash-newline pairs are removed
	3.  The file is decomposed into preprocessing tokens and white space
	    (including comments).
	...

If C++ is like ANSI C here, then it seems that the above sequence must be a
legal C++ comment.
