[PATCH 2/2] pass ls: Add --find flag

[Alejandro Colomar]

Similarly to `pass find --find`, this flag changes the `pass ls` command
to use find(1) instead of tree(1).

With this flag, the output is directly usable in a subsequent call to
`pass show`.

Examples of use:

	$ pass find --find kernel \
	  | tail -n -1 \
	  | xargs ./password-store.sh ls --find;
	www/foss/kernel/
	www/foss/kernel/smtp/
	www/foss/kernel/smtp/pass
	www/foss/kernel/bugzilla/
	www/foss/kernel/bugzilla/url
	www/foss/kernel/bugzilla/alx/
	www/foss/kernel/bugzilla/alx/id
	www/foss/kernel/bugzilla/alx/pass

	$ pass find --find kernel \
	  | tail -n -1 \
	  | xargs pass ls --find \
	  | tail -n1 \
	  | xargs pass show;
	pw

And here's a patch for pass ls.  These patches apply on top of the
formatting fixes for the manual page that I sent earlier.

Cheers,
Alex
