commit 7dc8f4bf7bc3bfde341d202228e83bcce82d6886

    don't try to find forward links in non-text files
    
    If a file extension is not in 'denote-file-types', we have no way of
    parsing or finding outgoing links in it. This change checks for the
    file extension early on in 'when-let*' block and avoids opening the
    file which is a relatively costly operation (and would fail finding
    links anyway).
