Description

When running Maven 2 by calling mvn.bat on Windows 2000 (SP4) the batch file sets M2_HOME to a value including the name of the batch file itself.
This results in an error:

ERROR: M2_HOME is set to an invalid directory.
M2_HOME = C:\maven\maven-2.0\bin\mvn.bat\..
Please set the M2_HOME variable in your environment to match the location of the Maven installation

When changing line 72 of mvn.bat to use %~dp0 instead of %~dps0 it works correctly:
if "%OS%"=="Windows_NT" SET M2_HOME=%~dp0\..

Looking at the SVN history, this was changed to %~dps0 to work with spaces
