man reader: indentation is lost for definitions spanning multiple paragraphs

[17dec]

Best shown with a minimal example:

$ cat test.man
.TH "EXAMPLE" "1"
.SH "OPTIONS"
.TP 8n
\fB\-\-help\fR
This is line one.
.sp
This is line two.
$ pandoc test.man -f man -t markdown
# OPTIONS

**\--help**

:   This is line one.

This is line two.

The second line is considered a separate paragraph from the definition list, but it should still be part of the definition.

Example as rendered by mandoc(1), which has the second line properly indented:

$ mandoc ./test.man -T ascii
EXAMPLE(1)                  General Commands Manual                 EXAMPLE(1)

OPTIONS
       --help  This is line one.

               This is line two.

                                                                    EXAMPLE(1)

Using pandoc 3.1.9, but can also reproduce on try pandoc.
