[glib/ebassi/gdbus-codegen-rst: 2/7] codegen: Do not add extra paragraph elements while parsing

[Emmanuele Bassi <ebassi src gnome org>]

commit 5013d0831517b77bd53ad6b770eee81eac03f5f2

    codegen: Do not add extra paragraph elements while parsing
    
    When parsing a comment we're adding <para> elements ourselves, but the
    DocBook generator already wraps any block of text that does not start
    with a <para> element with one.
