go get -u github.com/junegunn/fzf
works fine but want to test the development branch like so:
gert@gert ~/ GO111MODULE=on go get -u github.com/junegunn/fzf@devel
go: finding github.com/junegunn/fzf devel
go: finding golang.org/x/crypto latest
go: finding github.com/smartystreets/assertions latest

go: finding golang.org/x/tools v0.0.0-20190328211700-ab21143f2384
