Details:

The output of this command, run from the top of the groff source tree (or from
/usr/share/groff/current on a system with groff installed) is highly
questionable:

$ grep ^slant font/devps/T*
font/devps/TBI:slant 15
font/devps/TI:slant 7

It surely isn't correct that Bold Italic has twice the slant of Italic for the
ps device.  The slants appear visually identical (as they should), and the
slant values are identical in every other pair of Italic / Bold Italic fonts
in font/devps (grep ^slant font/devps/*), and nearly identical for Times
Italic and Times Bold Italic in every other font/dev* directory (grep ^slant
font/dev*/T*).
