Hmm, that's tricky. How do you propose that we solve it?

Currently we specify a name without the extension. On windows of course
most executables have a .exe extension so we automatically append that.

We don't want people to have to say:
executable: foo.exe

since then it's not portable to non-windows. So how can we infer that no
extra .exe extension is required? Is it reasonable to guess that if it
already has one '.' in the name that we shouldn't add a .exe extension?
