Absorb: ask for the passphrase once the archive starts arriving

Browse Source 
With gpg --decrypt x.tar.gpg | vault absorb, vault printed its prompt
while gpg was still writing to the terminal, which buried it, so the
command looked hung. Peek at standard input first: the upstream program
has finished with the terminal by the time data arrives, and an empty
pipe now fails without asking at all.

it still works with an archive piped in. The vault is locked exclusively
for the whole run.
