need info: %r in printf

_doprnt() came back in (at least the VAX version of) UNIX System V.
vsprintf() and friends were in UNIX System III (with one bug) but
went away in UNIX System V.  What is the "next release of UNIX System V"?
Any relation to USG 6.0?  Why can't the WECo developers make up their
mind about these things??
