File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
This works, but in my version of wxformbuilder there is a bug which does not properly show the
subclass property, even though it is still in play. This happens after saving then loading the *.fbp file.
So it is a nuisance bug, but does not affect functionality.
