Fixes the following vet reports:
config/lang/check_types.go:98: arg n for printf verb %d of wrong type: *github.com/hashicorp/terraform/config/lang/ast.Concat
config/lang/lex.go:80: arg x.mode for printf verb %s of wrong type: lang.parserMode
This fixes a bug where Terraform would error with the following:
```
Error loading config: Error reading
/Users/rhenrichs/work/example/.#example.tf: open
/Users/rhenrichs/work/example/.#example.tf: no such file or directory
```
The solution implemented here ignores the common emacs and vim
temporary file formats.
Note: the potential danger with merging this is that Terraform could
quickly have requests to ignore other file formats.
