Description

I am running a simple hello world style script.
The working directory has the following structure:

.
|-- lib
|   |-- commons-io.jar
|   `-- commons-lang3.jar
`-- src
    |-- Main.groovy
    `-- a
        `-- pkg
            `-- Hello.groovy

I am trying to run the following command:
groovy --classpath ".\lib*;.\src" src\Main.groovy

The error I get is: "The syntax of the command is incorrect."

Digging a little bit in the batch files called I traced the problem to bin\startGroovy.bat, specifically in :win9xME_args_slurp.
In that block, there is an attempt to replace * in various situations however my case uses \ (and /) which is not covered.
It seems to me that this is a rather common use case some I think it should be beneficial to add the following 2 lines in the script:

set _ARGS=%_ARGS:/*=/-s%
set _ARGS=%_ARGS:\*=\-s%
