safe variables for perl and cperl

[Tom Tromey]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


automake.in, a perl script, has this local variable section:

    ### Setup "GNU" style for perl-mode and cperl-mode.
    ## Local Variables:
    ## perl-indent-level: 2
    ## perl-continued-statement-offset: 2
    ## perl-continued-brace-offset: 0
    ## perl-brace-offset: 0
    ## perl-brace-imaginary-offset: 0
    ## perl-label-offset: -2
    ## cperl-indent-level: 2
    ## cperl-brace-offset: 0
    ## cperl-continued-brace-offset: 0
    ## cperl-label-offset: -2
    ## cperl-extra-newline-before-brace: t
    ## cperl-merge-trailing-else: nil
    ## cperl-continued-statement-offset: 2
    ## End:

Every time I visit this file I'm prompted to verify these settings.
I looked at perl-mode and cperl-mode, and only perl-indent-level and
cperl-indent-level are marked as safe local variables.

I think all of these variables should be marked as safe.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.0.990/etc/DEBUG for instructions.
