indeed.  thanks.

Now, how do I check that the next item after this comment is character
data?

I need

<!-- foo -->
bar

to go to

.\" foo
bar

Also, another problem is that

<varlistentry id="opt-libdir"><term><option>-B</option>
  <replaceable>lisp-lib-dir</replaceable></term>
 <listitem><simpara>Specifies the installation directory.
   This is the directory containing the linking sets and other data files.
<!-- #ifdef UNIX -->
   This option is normally not necessary, because the installation directory
   is already built-in in the <command>clisp</command> executable.
<!-- #endif -->
   Directory <replaceable>lisp-lib-dir</replaceable> can be changed
   dynamically using the symbol-macro <varname>*lib-directory*</varname>.
</simpara></listitem></varlistentry>

is translated into

.TP
\fB\-B\fR \fIlisp\-lib\-dir\fR
Specifies the installation directory\&. This is the directory containing the linking sets and other data files\&. .\"#ifdef UNIX This option is normally not necessary, because the installation directory is already built\-in in the \fBclisp\fR executable\&. .\"#endif Directory \fIlisp\-lib\-dir\fR can be changed dynamically using the symbol\-macro \fI*lib\-directory*\fR\&.

instead of

.TP
\fB\-B\fR \fIlisp\-lib\-dir\fR
Specifies the installation directory\&. This is the directory containing the linking sets and other data files\&.
.\"#ifdef UNIX
This option is normally not necessary, because the installation directory is already built\-in in the \fBclisp\fR executable\&.
.\"#endif
Directory \fIlisp\-lib\-dir\fR can be changed dynamically using the symbol\-macro \fI*lib\-directory*\fR\&.

I haven't lost my mind -- it's backed up on tape somewhere.
