bug#343: C mode asks twice about local variables

[Glenn Morris]

This applies in Emacs 22.2 and CVS trunk.

emacs -Q lib-src/etags.c

    The local variables list in etags.c
    contains values that may not be safe (*).

    Do you want to apply it?  You can type
    y  -- to apply the local variables list.
    n  -- to ignore the local variables list.
    !  -- to apply the local variables list, and permanently mark these
    values (*) as safe (in the future, they will be set automatically.)

    indent-tabs-mode: t
    tab-width: 8
    fill-column: 79
  * c-font-lock-extra-types: ("FILE" "bool" "language" "linebuffer" "fdesc" 
"node" "regexp")
    c-file-style: "gnu"


If I answer `y', nothing happens. I have to press `y' a second time.
