This makes the process of adding new regression tests pretty
annoying for everyone, which isn't really what we want.

Based on all experience with GLib, people really like 'make check'
to pass and file bugs liberally when it doesn't... having make check
fail until people do some sort of manual verification and replacement
doesn't sound like a good idea to me.

I'm already concerned about the Xlib failures on most servers.
