[pass] Patch: exit 1 when gpg fails in multiline

[the_jinx at etv.cx]

While I was working on QtPass I came upon a bug in pass where it exits 
with 0 when multiline inserts go wrong, for example when you have added 
someone to the .gpg-id file but not trusted his/her key.

As you can see it is a tiny little patch.

I have also made a pull-request for this
