[Groff] Bug in devdvi

[Robert D. Goulding]

Further on the weird integral from the dvi device.  It is not a hacked
integral, but the integral from cmtex (i.e., mathematical symbols for
typewriter text).

The following file:

.LP
\(is

processed with groff -ms -Tdvi -Z

gives the intermediate output:

x T dvi
x res 57816 1 1
x init
p1
x font 13 SC
f13
s1000
V67452
H57816
md
DFd
Cis
h4200
n9636 0
V616704
H404712
n9636 0
x trailer
V635976
x stop

So you see that groff is, unaccountably, mounting the SC font at font
position 13, instead of EX.  On the other hand, the file

.LP
\[ois]

behaves properly; the relevant lines of the intermediate output are:

x font 16 EX
f16
s1000
V67452
H57816
md
DFd
Cois

One other odd thing.  The following file:

.special EX
.LP
.EQ
int from 0 to inf
.EN

gets the correct integral from the EX font, but takes the *infinity*
symbol \(if from SC.
