unfortunately, there is no provision for proportional interline spacing.
i use cyberbit as my day-to-day font, and it has the problem you mention.
if i look at the font image with page (/lib/font/bit/cyberbit/cyberbit.14.0101),
the image looks correct, so the problem lies with the font height (technically
the extra decent), which unfortunately looks right for lines without tall
characters with an accent.

this is a great summer-of-code project, since it requires deep changes,
but not mysterious or complicated changes.  there is currently no per-
character height information in font(6) subfonts. one would also need
to add a stringheight(2) and work that into the various libraries and
programs, like

acme aux/statusbar, faces, gping, mc, p9bitpost, rio, samterm, plot, stats,
	trace, drawterm, abaco games/jukebox games/9clock libcontrol
	libdraw libframe
