[Mono-dev] sub-process invocation on posix

[Michael Hutchinson]

FWIW, you actually just need to double quote each argument and escape
double quotes so you can very easily write a helper to do this in a way
that works on both Mono and .NET:

static Process StartProcess (string name, params string[] args)
{
    string a = null;
    if (args != null && args.Length > 0)
        a = "\"" + string.Join (args.Select (s => s.Replace ("\"",
"\\\"")).ToArray (), "\" \"") + "\"";
    return Process.Start (
        new ProcessStartInfo (name, a) {
            ShellExecute = false,
        }
    );
}

Obviously this could be done more efficiently with a StringBuilder.

Apologies for any errors, I'm writing this on my phone...
