[pkg-go] Bug#868070: gocryptfs: '--version' option is useless, containing only 'gocryptfs'

[Unit 193]

Package: gocryptfs
Version: 1.3-1
Severity: normal

Dear Maintainer,

When you call `gocryptfs --version`, the only info you get back is 'gocryptfs'.
This is because the required vars aren't set at build time, with the below patch I get 'gocryptfs 1.3; go-fuse 0.0~git20170609.0.5690be4-1; 2017-06-17 go1.7.6'
