I think you didn't understand what I meant. The queue will not contain the
moved pages, but pages that link to moved pages and need fixing.
Say you want to move page :foo and pages :bar :baz are linking to :foo. :foo
will be moved, :bar :baz will be put in the queue. When you know visit page
:bar the plugin sees that it's listed in the queue to be fixed relative to the
moved page :foo and will fix all "old" links to the original page :foo bevor
you get to see the content of page :bar.

No, determining the pages which need to be fixed makes like maybe 5% of the
work and is the easiest part of the whole process ;).

This is just one extra file read operation, which is cheap compared to doing
everything at once. You could go further and only check if the timestamp of
the pagemove queue is newer than the page itself before doing an actual read
of the queue file - but I partly agree, this could be optimized.

I don't like that, too specialized. It's either a fix it all or leave it be
thing. Everything else is not what you (or in this case I) would like to
implement ;).
Thanks for all the input so far!
