Bug#647250: add check for init.d status option

[Peter Eisentraut <petere@debian.org>]

Package: lintian
Version: 2.5.3
Severity: wishlist
Tags: patch

I'm trying to move the issue of the init.d status option forward (see
ancient policy bug #291148).  During squeeze I supplied patches to a
bunch of the most popular packages, and most packages were so patched.
Now I'm in a second round of patching the most popular and highest
priority remaining packages, and it looks like we could have very high
support for this in wheezy soon.

So, at this point I figured it would be a good time to get a wishlist
check for this into lintian, to get the word out to the most eager
maintainers, and to allow easier progress tracking on
lintian.debian.org.  At some later point, I will try to move the
policy bug forward, and then this check could simply be upgraded to a
warning.

The way I've worded this check leaves it open for adding other
optional init.d options, so that in another 5 years we can try adding
the try-restart option using the same route. ;-)

Anyway, attached is the patch; let me know what you think.
