Copy task ignores all but first file returned by FileNameMapper

           Summary: Copy task ignores all but first file returned by
                    FileNameMapper
           Product: Ant
           Version: 1.5.3
          Platform: All
               URL: n.a.
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: eeaston@ptc.com


The documentation for org.apache.tools.ant.util.FileNameMapper states "Used to 
find the name of the target file(s) corresponding to a source file."  Note the 
use of the word "file(s)."

Further the API:
java.lang.String[] mapFileName(java.lang.String sourceFileName) 
shows that you can map a single file name to many.

However, the copy task ignores all but the first mapped file name.  See line 
489 of 1.5.3-1 source for org.apache.tools.ant.taskdefs.Copy:
        for (int i = 0; i < toCopy.length; i++) {
            File src = new File(fromDir, toCopy[i]);
>>>         File dest = new File(toDir, mapper.mapFileName(toCopy[i])[0]);
            map.put(src.getAbsolutePath(), dest.getAbsolutePath());
        }

Copy and potentially other tasks that know about mappers should be fixed to 
fulfill the expectations set by the FileNameMapper javadoc and API declaration.
