GoCoverage fails with cannot find package '-coverprofile'

[gataky]

Actual behavior

Executing :GoCoverage causes the following error:

vim-go: FAILEDvim-go: can't load package: package '-coverprofile': cannot find package "'-coverprofile'" in any of: 

Expected behavior

Coverage report to overlay buffer

Steps to reproduce:

Minimal main.go

package main

import "fmt"

func main() {
    fmt.Println("")
}

Minimal main_test.go

package main

import "testing"

func TestHandler(t *testing.T) {
    main()
}

:GoCoverage

Configuration

I can run coverage outside of vim just fine.

:GoTest works as expected

I know support for neovim is in beta but I poked around in the coverage.vim file and saw conditions for nvim so figured that it may be supported. That's about the extent of my vimscript debugging sadly.

• vimrc you used to reproduce

call plug#begin('~/.config/nvim/plugged')
Plug 'failt/vim-go'
call plug#end()

• vim version:
  neovim 0.1.4
• vim-go version
  vim-go 1.7.1
• go version
  go version go1.6.2 darwin/amd64

Hi @sir-wiggles

Just discovered this myself too in Neovim. If you run it in Vim you'll see there is no problem. Must be something that was introduced with the latest version. I'll take a look at this. Thanks.

Alright it's broken due this line:

https://github.com/fatih/vim-go/pull/869/files#diff-a3998a862a20bc1665a15c84f401349fR200

Not sure how to fix it without pulling it out. We only need to escape the file after -coverprofile , but not the flag itself. Checking now.

The fix in master. Thanks for the feedback.

Wow you're fast! I was taking my first dive into vim scripting with this and was WAY off. 😛

Thanks for the amazing work!
