I'm working on a little Perl ditty to do a 3-way compare on text.dat 
files.  It assumes that there has been a fork where an original file was 
modified, and now a new version of the original has been released.

It compares all three files line-by-line and works on the premise that:

1)  If the new verion does not differ from the old, (no official change) 
    then the users version, modified or not, can be used.

2)  If the users version does not differ from the original, so the new 
    version (changed or not) can be used.

3)  Otherwise, the three files are all different and it's decision-time as
    to whether to use the users modified line or the official updated 
    line.

In case #3, what would you suggest the program do?  I don't know if it 
makes more sense to go with the users modified version, the official new 
version, or both (with one commented out, and if so, WHICH one...)
