[PATCH] jakarta-ant HEAD branch

[Patrick Luby <pa...@sun.com>]

Attached is a patch to the ant and antRun scripts in the src/script 
directory. This patch does the following:

1. Removes the extraneous "cd `dirname $PRG`" line that causes the
    script to break when Ant is invoked with from a relative path
    (i.e. ../jakarta-ant/bin/ant).

2. Properly quote all environment variables that may contain paths.
    The script would break if any of these environment variables
    contained paths with spaces in them (a common occurrence on Windows).

3. Invoke Java using the "exec" shell command. There really is no need
    to create a child process to run the JVM and by using the "exec"
    command, there is less chance that killing the script will fail to
    kill Ant.

If these patches are OK, can someone please commit them?

Thanks,

Patrick
