    org.el: Preserve case for link subgroups from `org-file-apps'
    
    * lisp/org.el (org-open-file): Avoid matching of `org-file-apps' records
    against the link converted to downcase since it caused incorrect
    substitutions to the command.
    
    Consider the following entry
    
        (add-to-list
         'org-file-apps
         '("\\.PDF\\(?:\\.[gx]z\\|\\.bz2\\)?::\\(#[^:]*\\)::\\(.+\\)\\'"
          . "okular --find %2 -- %s%1"))
    
    and the link
    <file:///usr/share/doc/bash/bashref.pdf::#Redirections::before>
    Without the patch
    
        okular --find before -- /usr/share/doc/bash/bashref.pdf\#redirections
    
    command is executed and the application can not resolve internal
    cross-reference anchor.

    the purpose of `dlink' is not clarified, so I assume that the only
    purpose is to allow matching file suffixes, e.g. ".pdf" vs ".PDF".
