    ui.msgarea: Work around wrapping label allocation issues (#588)
    
    It's unclear what the bug here is, and I haven't been able to narrow it
    down well enough for a GTK bug report. In Meld, this problem manifests
    as the window getting a large fixed minimum allocation - apparently on
    the GtkScrolledWindow child, but I haven't tracked it down - when the
    GtkInfoBar has *two* child labels *both* of which use WORD_CHAR or CHAR
    wrapping.
    
    Since this bug does not show up if either label has WORD wrapping, here
    we're working around the problem by removing the WORD_CHAR wrapping from
    the secondary label. Since this wrapping was added to fix a bug in the
    primary label display on Windows, this seems like our best option.
