Allow <ant> to support multiple targets

           Summary: Allow <ant> to support multiple targets
           Product: Ant
           Version: 1.6Alpha (nightly)
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: jan@materne.de


I have modified <ant> to support multiple targets like
	<ant target="target1,target2"/>
so the buildfile doesn�t have to parsed multiple times and target-dependencies
should be solved.


I have used the java.util.StringTokenizer for that. 


An "fc /L /N Ant.java Ant.java.original" gave me (on windows 2k):
***** Ant.java
  398:             if (target != null) {
  399:                 // Support for multiple targets separated by commas
  400:                 if (target.indexOf(",")>0) {
  401:                     java.util.StringTokenizer targetNames
  402:                         = new java.util.StringTokenizer(target, ",");
  403:                     java.util.Vector targets = new java.util.Vector
(targetNames.countTokens());
  404:
  405:                     while (targetNames.countTokens() > 0)
  406:                         targets.add(targetNames.nextToken());
  407:
  408:                     newProject.executeTargets(targets);
  409:                 } else {
  410:                     // single target
  411:                     newProject.executeTarget(target);
  412:                 }
  413:             } else {
  414:                 // default target
  415:                 newProject.executeTarget("");
***** ANT.JAVA.ORIGINAL
  398:             if (target != null) {
  399:                 newProject.executeTarget(target);
  400:             } else {
  401:                 newProject.executeTarget("");

I have attached the Ant.java (modification based on Ant.java from CVS head 
5.Feb 03 13:08). Should I spent
some more time for doc�s and code for contribution?
