1.78.1 manpages glitch?

[Paul DuBois <paul@kitebird.com>]

I'm noticing a difference in manpage production with 1.78.0 versus 1.78.1.

Consider this input:

        <listitem>
          <para>
            <indexterm significance="normal">
              <primary>mysql-stress-test.pl</primary>
              <secondary>help option</secondary>
            </indexterm>

            <indexterm significance="normal">
              <primary>help option</primary>
              <secondary>mysql-stress-test.pl</secondary>
            </indexterm>

            <option>--help</option>
          </para>

          <para>
            Display a help message and exit.
          </para>
        </listitem>

1.78.0 output is okay, with the <indexterm> elements written as groff comments terminated by newlines

.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
.\" mysql-stress-test.pl: help option
.\" help option: mysql-stress-test.pl
\fB\-\-help\fR
.sp
Display a help message and exit\&.

1.78.1 output loses the newlines after the indexterm elements. The result is that the option
value (\fB\-\-help\fR) is glued onto the end of the long comment line. So of course it disappears
from the output of nroff -man and the resulting man page doesn't show the option. :-)

The only manpages difference I see between 1.78.0 and 1.78.1 occurs here:

If I change the 1.78.1 utility.xsl comparison from != to the = comparison used in 1.78.0, the output reverts to the correct form (with newlines included).

I see no other difference in the output.
