Not where I come from (i.e., p.181 of K&R, ed. 1).  The only time a quote-
within-a-quote should give you trouble is when nesting the quotation mark
within a quotation of its own ilk:

	'\''   is the character constant for single-quotation mark;
	"\""   is the "string pointer" pointing to a double-quotation mark.

Note that the converses-- '"' and "'" --require no backslash.
