[Groff] Ellipsis and Cdots

[Cedric Sodhi]

Hello,

according to man eqn an ellipsis of three subsequent dots will be
replaced by a real ellipsis, whereas to get three centered dots one
should use cdots.
However when I enter ... I get cdots and I wouldn't know how to get a
real ellipsis, since there does not appear to be an ellipsis glyph in
groff_char either (typing "..." will insert three mal-aligned dots).

Can anyone shed light on this? Thanks
