Allow duplicated classes and loosen source file name limitation in data file

Name: kbR10066 Date: 10/01/2001


Some of Jcov utilities (report generator, merger) enforces too strict limitations
on the jcov data file (s) structure being processed. Namely, it is not allowed for a jcov data
file to contain a duplicated class coverage data, and source file name can't contain
some characters allowed by most file systems (e.g. '[' or space character).

To reproduce, run the merger utility on the following data file below (a.jcov):

> java -cp jcov.jar javasoft.sqe.jcov.MergerMain a.jcov

Report generator will report an error. The correct behaviour would be:
1. to allow any chracters other than <end-of-line>s in the source file name
2. When a duplicated class coverage data is encountered, it should be merged
   with the existing data for this class.
