    Fix prefix discovery for files with read-symbol-shorthands (bug#67325)
    
    In a previous commit, the local-variable read-symbol-shorthands is
    already read into the temporary buffer used for the autoload parsing
    aerobatics, so all we needed to do in 'l-g--compute-prefixes' is
    use 'read' to give 'read-symbol-shorthands' a chance to kick in.
