// 2) It looks for the shortest prefix of command that is separated by space from the rest of the command that is either
// a) An absolute path to an executable file.
// b) Try prepend paths from ENV['PATH']
// c) Try Environment.SpecialFolder.System.
// d) Try SHGetFolderPath(CSIDL_WINDOWS) - we can't get this from Environment.SpecialFolder, so we need to use
// ENV["SystemRoot"] environment variable.
// In each step it tries to append ".exe" or ".com" extension if the path doesn't exist.

// For example, if the command is `x/a b/x` and the directory structure is
// x\a b\x.exe
// x\a.exe
// it executes a.exe.
//

// lpCommandLine == command. System.Diagnostics.Process also uses this API with lpApplicationName == NULL and
// lpCommandLine == '"{ProcessStartInfo.FileName}" {ProcessStartInfo.Arguments}'.

// Although CreateProcess does all the searching for an executable if passed no lpApplicationName,
// we need to do it ourselves because it is slightly different in MRI (is that a bug?) and also because System.Diagnostics.Process
