Stray T} in tbl mode

Stray T} in tbl mode

[Christian Neukirchen]

The following table, simplified version of Linux socket(2) misrenders:

\f
.TH SOCKET 2 2015-03-29 "Linux" "Linux Programmer's Manual"
.SH SYNOPSIS
.TS
tab(:);
l l l.
Name:Purpose:Man page
T{
.BR AF_UNIX ", " AF_LOCAL
T}:T{
Local communication
T}:T{
.BR unix (7)
T}
T{
.B AF_INET
T}:IPv4 Internet protocols:T{
.BR ip (7)
T}
.TE
\f

The final T} appears in the output, and ip(7) ends up as first entry
of line 3, not third entry of line 2, as it should.

(Moving "IPv4 Internet protocols" into its own line and wrapping it in
T{...T} helps...)

Renders OK in tbl/groff and plan9port tbl/nroff.

I just fixed this in OpenBSD and in mdocml.bsd.lv, too.

Thanks again for reporting,
