goreleaser: Main file distributed to separate files doesn't work

Prerequisites

• Are you running the latest version?
• Did you perform a search to see if this problem was already reported?

For more information, see the CONTRIBUTING guide.

Description

After I split my main.go into main.go & account.go, goreleaser stop to build it correctly.

Environment

Please paste the output of:

• go version

go version go1.9.1 windows/amd64

• uname -a

MINGW64_NT-6.1 dulanov-PC 2.9.0(0.318/5/3) 2017-09-13 23:16 x86_64 Msys

Steps to Reproduce

1. [First Step]

Split main.go into separate files lie in same main package.

1. [Second Step]
2. [and so on…]

Expected behavior: [What you expected to happen]

goreleaser process all files from main package.

Actual behavior: [What actually happened]

goreleaser process only tiny main.go and ignore completely other files from the main package.
