    mountd: Update exports.5 for commit 7c5146da1286
    
    Commit 7c5146da1286 modified mountd so that it uses
    strunvis(3) to decode directory names in exports lines.
    This allows special characters, such as blanks, to be
    encoded in the directory names.
    
    This patch updates the exports.5 man page for this change.
    
    This is a content change.
