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.

THIS IS A DRAFT
After much demand for a "team pass" that can live within git, and
instead of relying on gpg.conf for this, I've started to implement
a proper team pass.
Please tell me what you think of this. I want to get it right. Does
it satisfy the demands folks have had? Is it implemented as cleanly
as possible? Feedback wanted.
