This is simple enough to warrant a re-implementation to avoid spawning
subprocesses.

Anchor ignore lines

The lines written to the gitignore file by write-gitignore were not
anchored. This means that a line like

  !.zsh

might cause not only ~/.zsh to be ignored, but also ~/TODO/.zsh, which
is potentially a problem.

This patch simply prepends a '/' to each entry in the gitignore file,
thereby anchoring the entry to the repository root.

Note that the initial '*' must not be anchored, else files in
subdirectories wouldn't be ignored.

I don't think information about which hooks are run should be shown
unless -v is given.

This take the prize as most useless commit to the repo, yet.

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()

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