You're right about the SVID (Issue 3 as well as Issue 2) implying that
the two adjacent character codes '\' and 'n' in the format string are
treated as meaning "output a new-line".  However, that is simply a
mistake in the SVID, which should have called these "control characters"
or better yet have described the control actions separately from the
printf() description.

In fact, such an implementation would run directly counter to the C
Standard (which requires that these "ordinary characters" be output
without interpretation by printf()), and AT&T has indicated that that
was NOT their intent.

Presumably, if you bring this to AT&T's attention it might get fixed
in a future Issue of the SVID.
