I think it probably has more to do with font-width metrics: it looks
as though the italic characters are given the widths of corresponding
Roman characters, so that as italics the bottom sticks out a bit to
the left and the top sticks out a bit at the right of their metric
boxes, with the above effect in italic script; but then of course a
preceding Roman treads on the tail of the following italic; while a
following Roman gets head-butted by the preceding italic!

As to where it's coming from, I don't know. It may be a deliberate
design decision by the X font designers, in order to achieve the
pleasing joined-up effect (I see you're using an Apple ... !).


Hmm, can you tell me how the groff metrics were generated for the X fonts, or are these inherited from pre-groff days? The Times fonts used by X (on OSX or anywhere else, I'm guessing) are pcf fonts - how can the groff metrics be generated from these?

I suppose an alternative would be to switch to Type 1 or Truetype fonts for X display, and use afmtodit to generate the metrics (would that work?) - but even thinking about installing X fonts gives me a headache...
