This relies on a patched version of tree to work, unfortunately.
Hopefully upstream will accept our patch.

Some users want to use a different clipboard for pass.

The .gpg-id file may now have multiple keys in it, one per line.

If a .gpg-id file exists inside a subdirectory, passwords inside that
directory are encrypted to that/those ids.

The init command has learned a -p/--path option for writing such a sub
directory .gpg-id and now can take several arguments for ids.

Get rid of push/pull shortcuts, as they weren't widely used.
Add contents to repo on git init.
Centralize git add logic, and make it less error prone.

Laurent asked for this.

A user made this request:

    I was wondering whether it is in a planning to have multiple
    password-store directory trees or possible to achieve? eg.
    $HOME/.pwd-store-work and $HOME/.pwd-store-home. Maybe distinguish them
    with a command line switch and then create aliases in .bash_aliases?

    Why I'm asking is that I have multiple major password categories -
    personal, work etc. It'll be nice to keep them separate and under
    different repos.

This allows users to edit password files using temporary files created
in /dev/shm. This commit also tidies other things up and fixes minor
bugs and griviences that should be separate commits but aren't.

Add a --no-echo flag to the insert operation so that the password isn't
echoed when entering it. This requires the user to echo the password
twice for confirmation.
