I support the idea of renaming one of these files.  Not to make things 
work on case-insensitive filesystems, but simply because having two 
files with rather long (and almost nonsensical) names that are identical 
aside from one single letter is an excellent way to confuse users.

Come on -- just look at the error report above.  Can you tell at a 
glance, without going through and carefully comparing the two strings 
letter-by-letter, exactly what the difference is?  Do you really think 
anybody could?

I haven't looked to see if there are any other similar examples in the 
litmus-tests directory, but if there are than they should be changed 
too.
