Ted, I'm sorry that I haven't made myself clear.
My concern is that the \Y[...] way of injecting PS into groff
interferes with the text.
In SGI-troff with Adobe's prologue they were absolutely independent,
linked only via a CP so, foolishly I expected that 'ps: ..' would not
generate anything but graphics.

Perhaps later I'll find some use for groff's different way of doing it.
Now I'd like a quick transition 'cause I have a lot
of PS inserts and there's something about old dogs & new tricks.

You suggested a backslash, Werner suggested \c and they work if the \X 
thing is part of the text.
However, \Y[...] followed by a call to a macro is a different cattle of 
fish:

    .bp
    \Y[draw-a-grid]
    .macro-starting-with-an-indent

Here I can't use \, \c does not work, the macro inherits a space and
indent drops a line.

Currently I hide the \Y in a macro, followed by .sp -1 and use the 
macro instead of  \Y in the main text.
It's not a tragedy, just finding a hiding place for every PS insert, if 
indeed this is the only to do it, is quite a bit
of inconvenience.

Thanks to you and Werner,

Miklos
