Can't stack exec a .bat file #2225
Description
Given a batch file hello.bat I can run it from the Windows command line with hello, hello.bat, cmd /c hello and cmd /c hello.bat. When running stack exec -- ... for any of those 4 variants, using stack-1.1.2 i386, I get one of:
C:\Neil\temp\stack-bat>stack exec -- cmd /c hello.bat
Run from outside a project, using implicit global project config
Using resolver: lts-2.14 from implicit global project's config file: C:\Users\ndmit_000\AppData\Roaming\stack\global\stack.yaml
C:\Users\ndmit_000\AppData\Local\Programs\stack\i386-windows\msys2-20150512\usr\bin\cmd: createProcess: invalid argument (Exec format error)
C:\Neil\temp\stack-bat>stack exec -- hello.bat
Run from outside a project, using implicit global project config
Using resolver: lts-2.14 from implicit global project's config file: C:\Users\ndmit_000\AppData\Roaming\stack\global\stack.yaml
Executable named hello.bat not found on path: ["C:\\Users\\ndmit_000\\AppData\\Roaming\\stack\\global\\.stack-work\\install\\1fc798c0\\bin","C:\\Users\\ndmit_000\\AppData\\Roaming\\stack\\snapshots\\0ac80986\\bin","C:\\Users\\ndmit_000\\App
... ]
The .bat suffix does not seem to make a difference.
