start is a cmd builtin, doesn't work for edit

[quinnj]

Ran into this trying to use the edit methods, but it seems like a spawn issue to me.

shell> start C:/Users/karbarcca/code/scratch.jl
ERROR: could not spawn `start C:/Users/karbarcca/code/scratch.jl`: no such file

#below works no problem; same command
C:\Users\karbarcca>start C:/Users/karbarcca/code/scratch.jl

Have seen this bug in a few packages. I think you need to do cmd /c start C:/Users/karbarcca/code/scratch.jl

Ah, that did it. So is there something that needs to be fixed here?

Find every usage of start for opening files on Windows in base and/or packages and prefix them with cmd /c ?

[vtjnash]

The command for this is ShellExecuteEx, which is for launching windows GUI applications (whereas the current API is for launching command line applications): http://msdn.microsoft.com/en-us/library/windows/desktop/bb762154(v=vs.85).aspx

Ok, I've got a working version of ShellExecute. So should we use that for the edit function and cmd /c for shell mode?

The replacement with ShellExecuteW seems complete, InteractiveUtils doesn't use start anywhere, and the rest of base and stdlib don't seem to either. This can probably be closed.
