[Xy-pic] dvips breaks \newgraphescape in graph feature

with the same with "dvips," deleted:


The first example produces the following cryptic error message:

! Illegal parameter number in definition of \xyPSdictknown@.
<to be read again>
l.169  \DNii@
             {\xywarning@{You did not type Y or N -- try again please}%

while the second example is processed just fine.

Presumably the dvips feature is breaking the processing of arguments to
\newgraphescape?  Things *seem* to work ok if I don't try and use
arguments, though I haven't tried very much yet.

Is this a known problem?
