Bug#373976: apache2-common: a2dissite rewritten to allow globbing/multiple site disabling/includes man page

Package: apache2-common
Version: 2.0.54-5
Severity: normal
Tags: patch

I have modified a2dissite to :

1. disable multiple sites at a time, (including file globbing).
  (Both from the command-line, and from the "Site Name?" prompt)
2. modified the sites-enabled listing to be columnar, as opposed to space-delimited. 
  (Helps when you have hundreds of sites enabled).
3. allow for interactive or non-interactive modes, (using -f). 
  (interactive mode prompts for confirmation before disabling a site). 
4. generates a help message (-h).
5. I also wrote a man page "a2dissite(8)", which documents all of the features that
I have included in this revision:

.TH a2dissite "8" "June 2006" "a2dissite"
a2dissite \- Disables Apache2 sites
.B a2dissite
[\fIOPTION\fR] [\fIFILE\fR] [\fIFILE\fR]...

.B a2dissite
simplifies the relationship between available and 
live, (or enabled), sites, by creating a user interface which controls
the creation of symbolic links between configuration files
in /etc/apache2/sites-available and /etc/apache2/sites-enabled.
.B a2dissite
allows you to pass the names of configuration files, (which exist
in /etc/apache2/sites-available), from the command line, or will
generate a listing of available sites if no arguments are given.  
(File globbing is available).
run in non-interactive mode, (do not prompt user for confirmation when enabling a site).
display help message and exit
.B a2dissite
Generate a list of 
.B available 
sites and prompt for user to input a list of sites which they would like to disable.  
This runs a2dissite in default 
.B interactive 
mode, and will prompt the user for confirmation before disabling any site.
.B a2dissite -f
Same as previous example, except that it runs a2dissite in
.B non-interactive
mode. (It will not prompt the user for confirmation before
enabling a site).
.B a2dissite default
Enables the default site. (interactive mode)
.B a2dissite \-f default test2? test1
Enables the default site, plus test1, and all of the sites which 
match the globbing pattern test2?, (ie test20, test21, ... test29). (non-interactive mode)
