[Mingw-msys] Follow-up on msys.bat

[Randy W. S. <RandyS@ThePierianSpring.org>]

Earnie,

I just discovered an error in that batch script I recently posted that
didn't show up in my previous tests. If you use it change the first line
from:

if "%1" == "GOTO:" %1%2
  --to--
if "%1" == "GOTO:" goto %2

This avoids the error: "The syntax of the command is incorrect."
which appears when no arguments are passed on the initial invocation. I
don't know how I missed that one. <:-0

Randy.
