Solaris 9 'man' command runs afoul of groff 1.19 SGR

[Paul Eggert]

GROFF VERSION:
1.19

MACHINE:
SunUltra 1/170E

OS:
Solaris 9

COMPILER:
GCC 3.3

INPUT FILES:
none

COMMAND LINE:
man sh

DESCRIPTION OF INCORRECT BEHAVIOUR:
The output looks terrible; there are all sorts of [m's in it.

The problem is that Sun's "man" command runs
"nroff -u0 ... | col -x".  Groff's nroff outputs SGR commands,
but the Solaris 'col' command doesn't understand them and
strips off the escapes.

SUGGESTED FIX [optional]:

2003-06-06  Paul Eggert  <address@hidden>

        * src/roff/nroff/nroff.sh: Disable SGR when ignoring -u.
