See my other post in this thread where strace shows @ handling is not involved, as the script directory and name are normalized and converted to a win32 path correctly, but child_info_spawn::worker does not appear to quote args with spaces (or apostrophes) when building the command line, despite the comment near the top of the function. It is not clear where this quoting is expected to be done: it looks like child_info_spawn::worker may do this itself when a script is invoked as "cmd|command /c script" with argc == 3, but may be expecting a called function to do this for other cases, as for a cmd script with no args and argc == 1. -- Take care.
