[PATCH] pass find: Add --find flag

[Alejandro Colomar]

This flag modifies the command to use find(1) instead of tree(1).

A few tweaks are performed to the result of find:

(1)  Add a trailing slash to directories.  This is a useful way to
     distinguish files from dirs at first glance.  In the tree(1)
     version, it colors differently (as tree(1) does by default), so it
     seems consistent to distinguish them.

(2)  Remove the location of the password-store prefix from the path.

(3)  Remove the .gpg suffix from files (as is historic behavior of
     pass(1)).

Examples of use:

	$ pass find --find bugzilla
	Search Terms: bugzilla
	www/foss/kernel/bugzilla/
	www/foss/mozilla/bugzilla/
	www/foss/gentoo/bugzilla/
	www/foss/gnu/gcc/bugzilla/

	$ pass find --find kernel
	Search Terms: kernel
	www/foss/kernel/

Those tweaks to the output of find(1) make the output directly usable in
a subsequent invocation of pass(1):

	$ pass find --find kernel \
	  | tail -n -1 \
	  | xargs pass show;
	www/foss/kernel
	├── bugzilla
	│   ├── alx.manpages
	│   │   ├── id
	│   │   └── pass
	│   └── url
	└── smtp
	    └── pass

The tail(1) above is to hide the search terms.
