We might bring back the self-updater at some point, but right now it's
dead code and it's not clear to me how to implement it in a fashion
where it also updates dependent files such as shell completion scripts
and man pages.
After the last howeyc/gopass update, hitting Enter after password input
makes the next printed line appear indented to the position of the
password prompt. I'm not sure what causes this, but as a workaround,
skip the howeyc/gopass dependency altogether and interface directly with
crypto/ssh/terminal.
Fixes#1262
