Git repos place the files as write-protected by default, so the
vcsh delete operation requires the user to typo 'y' repeatedly as the
repo is deleted. Using -f removes the repository properly.

See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=699093 for details

Previously, only -d would shift parameters from the option stack
correctly.

Fix mistake and improve wording in help()

Was: "Help isn't showing correct number of <repo>"

Supported files

* /etc/vcsh/config
* $XDG_CONFIG_HOME/vcsh/config
* vcsh -c <file>

See commits

* be8779f7ac9a3be9aa783df008d59082f4054f67
* 95e7705310bce3b2721ebf789776c170cf424abb

in git's git repository

* -c:
  Source <file> prior to other configuration files
* -d:
  Enable debug mode
* -v:
  Enable verbose mode

This should help users of Debian Wheezy find their way to a potential future
backport.

* Point out that Debian packaging lives in branches in this repo
* Ask third parties to contribute their work so it can be included

use git shortlog and .mailmap to remove duplicates

When using the basic log command one of the authors shows up twice:

zsh» git log --all --format='%an <%ae>' | sort -u -k2
Vincent Demeester <vincent@demeester.fr>
Richard Hartmann <richih+github.com@richih.org>
Richard Hartmann <richih.mailinglist@gmail.com>
Dieter Plaetinck <dieter@plaetinck.be>
Corey Quinn <corey@sequestered.net>
Gernot Schulz <post@gernot-schulz.com>

If you instead use the git shortlog version with the .mailmap file you get:

zsh» git shortlog -se --all | cut -f1 --complement | sort -u -k2

Vincent Demeester <vincent@demeester.fr>
Richard Hartmann <richih.mailinglist@gmail.com>
Dieter Plaetinck <dieter@plaetinck.be>
Corey Quinn <corey@sequestered.net>
Gernot Schulz <post@gernot-schulz.com>

Alphabetical sorting on the second field (which, incidentally, may be a middle
name) is preserved.

don't echo the command when doing make moo

Thanks to Mathdesc for catching that one.
