I don't see how it makes any difference, really. Take
XChangeDeviceControl.man, for instance. Rather than just waiting for
XGetDeviceControl.man to show up, it will now wait for all the real
manpages to show up. It really shouldn't need to do that for any
reason. Now consider the situation where XChangeDeviceControl.man
doesn't exist for some reason. We want to trigger
XGetDeviceControl.man to get rebuilt, but now the rule has all the
real pages as prerequisites. This will cause all the pages to get
removed and rebuilt. It's a pretty big hammer, but it would work if
you're not confident in the approach that's in there.

Also, I played around quite a bit this morning on this and I'm pretty
sure that what's in their now works.
