pass choose

[Philippe Biondi]

Hello,

I've always been lazy, and I also tend to forget where I put my stuff.
For the second point, "pass find" was a benediction. But once the path
I'm looking for has been found, I find it painful to enter it again with
a new invocation of "pass". Even more painful that I already entered
enough to find it.

So I wrote this little quick patch to add a "choose" command:

    pass choose [pass-names...]
    	List passwords that match pass-names and ask to choose one

It works a lot like "pass find", except that:
- when only one file has been found, it is decrypted
- when many files have been found, a choice is asked and the chosen file
  is decrypted

Ex:
-----------8<---------------
$ pass choose mast
Search Terms: mast
    ├── work
    │    └── bank
  1 │         └── mastercard
    └── infra
         └── masterdb
  2           ├── console
  3           ├── db
  4           └── infrasys_volume
Choose a line: 1
Choosing: work/bank/mastercard

Please enter the passphrase to unlock the OpenPGP secret key:
[...]

The following patch is only a preliminary work on a late night and I
probably forgot one thing or two. But if you find this useful and are
willing to integrate it, let me know what is missing to have it accepted.
