fresh-line misbehavior

[David T. <dv...@da...>]

         (princ "xxx")
         (terpri *standard-output*)
         (princ #\Tab *standard-output*)
         (fresh-line *standard-output*)
         (princ "yyy")


prints two lines in CLISP, both 2.33.2, and current CVS.

xxx
	yyy

It should print three lines

xxx

yyy

because while #\Tab is a semi-standard character, if an implementation 
recognizes it, it is a character on the line, and the printer and not 
at the start of a new line anymore. CMUCL, Lispworks, Allegro Common 
Lisp, Open MCL and ABCL print three lines.

I am posting it here instead of submitting a bug in sourceforge because 
I am not sure whether it is a bug or a design.
