Readonly bit use case

Hi all,

I've just encountered a use case for the read-only bit.

If you have files that are generated files, but you want to version
them, you still don't want people hand-editing them.  So you can mark
them read-only, and have the script that generates the file work around
the fact that it's read-only.

This is obviously somewhat questionable-- a more correct approach would
be to avoid versioning generated files.  But for various reasons, it is
sometimes desirable.

In the case of the files we have at PanoMetrics, there is a cpp file
that is generated, (in a mostly-cpp tree) and it's nice to be able to
update the source file, generate the cpp, and see that the cpp has been
updated correctly in the diff.
