8218 :: Misleading error message from startProcess()

  Hello dear community,

  I want to inform you about a bad error message that occurs when you call startProcess with a wrong workingDir. (I hope the category is the right one)

  const correct_path = "/home/user/"
  const wrong_path = "home/user/
  #Works fine:
  let p = startProcess("ls", correct_path)
  #Gives the following error message:
  let p2 = startProcess("ls", wrong_path)
  Run

  The error message is the following:

  
  ref 0x7f25edd83b90 --> [errorCode = 0,
  parent = nil,
  name = 0x560c625722e2"OSError",
  msg = 0x7f25ea28f060"Additional info: \"Could not find command: \\'ls\\'. OS error: No such file or directory\"",
  trace = 0x7f25edb4f150@[[procname = 0x560c6259d322"foo",
  line = 50,
  filename = 0x560c6259d1c8"/home/container/foo.nim"], [procname = 0x560c6259d1c0"main",
  line = 45,
  filename = 0x560c6259c1c0"/home/container/foo.nim"], [procname = 0x560c6259be9a"startProcess",
  line = 1016,
  filename = 0x560c6259bd58"/home/container/.choosenim/toolchains/nim-1.4.8/lib/pure/osproc.nim"], [procname = 0x560c6259be86"startProcessAuxFork",
  line = 1126,
  filename = 0x560c6259bd58"/home/container/.choosenim/toolchains/nim-1.4.8/lib/pure/osproc.nim"], [procname = 0x560c625722ea"raiseOSError",
  line = 94,
  filename = 0x560c62572288"/home/container/.choosenim/toolchains/nim-1.4.8/lib/pure/includes/oserr.nim"]],
  up = nil]
  Run

  Could not find command: \\'ls\\' is very misleading and it took me a couple of hours to debug until I coincidentally found out that it works without the workingDir. So maybe there should be a more precise error message with parameter checking.

  Greetings, Christian
