If changes to sprintf behavior are being considered, would it
be possible to allow some of the other K&R conversion
specifiers?
xX - for integer to hex conversion, and
c - for ascii value to character conversion
would all be useful for me.
Thanks, Steve Dutky

+I have thought about this, but it is not really clear what
the right thing

+
+sprintf(("%04d %s", 1:3, "abc")
+
+do? Produce a character vector of length 1 or 3? If of
length 1,
+"0001 0002 0003 abc" or "0001 2 0003 abc"?
+
+I guess the most R-like thing would be to recycle args to
the length of

done fairly
