Summary: CVS.pm does not work with branching tags

Initial Comment:
LXR version: 0.9.10
No indexes are created for branched tags
Using CVS.pm
----------------------

The "CVS.pm" code for "sub parsecvs" does not work with branching tags.  No indexes are created for them.

For branches RCS version numbers contain a "0" to indicate they are a branch.  When mapping 'symbols' to a real revision number the code needs to find what actual revision number for a branching tag is.  

Currently for a branched tag  the parsecvs function looks through the rcs file and finds that a branching tag (ex: FOO) is associated with revision (ex: 1.2.0.3).  But that isn't an actual revision number 1.2.0.3.  So we need some additional code in the parsecvs function to find the actual revision number for branched tags.

I am attaching an example of some code that appears to solve the problem.  (I don't claim to be an expert on the RCS file format but I looked at a few rcs files and found a pattern that seems to hold up)
