As man pages are now, one will see weird quotes regardless
of how \(oq is rendered.

I checked /usr/share/man1/[a-c]* in Fedora Linux--about a 10%
sample of man1. Only 2 out of 328 pages contained \(oq or \[oq].
By contrast, 80 pages contained ` (0x60) used as a left quote, 
usually paired with ' (0x27) but (surprisingly) sometimes with \(aq.

Although it might help to render \(oq as ' on man pages,
it would be wrong to render 0x60 that way, lest examples
in which the distinction matters be mutilated.
