  Modified:    .        CHANGES
               src/java/org/apache/oro/text/regex Perl5Matcher.java
  Log:
     Fixed bug whereby compiling an expression with
     Perl5Compiler.MULTILINE_MASK wasn't always having the proper effect
     with respect to the matching of $ even though
     Perl5Matcher.setMultiline(true) exhibited the proper behavior.  For
     example, the following input
      " aaa bbb \n ccc ddd \n eee fff "
     should produce "bbb ", "ddd ", and "fff " as matches for both the
     patterns "\S+\s*$" and "\S+ *$" when compiled with MULTILINE_MASK.
     Perl5Matcher was only producing the correct matches for the second
     pattern, producing only "fff " as a match for the first pattern
     unless setMultiline(true) had been called.  This has now been fixed.
  
  Thanks go to "Anders Cederlund" <anders.cederlund@biglandscape.com>
  for reporting this problem.

    o Fixed embarrassing bug whereby an expression like (A)(B)((C)(D))+
      when matched against input like ABCDE would produce matching groups
      of: "A" "B" "" null "D" instead of "A" "B" "CD" "C" "D".
