docs: // PathCmder returns a Cmder that runs the command at the supplied path with the specified "prependedArgs" provided as
  // arguments to the executable before all of the other arguments that are added. The path should resolve to the
  // executable that should be run: for example, "/usr/bin/git". The "prependedArgs" will be combined with the arguments
  // provided to the Run method for any given execution.
