rename hook: instead of modifying the passed-by-name array, return a copy

[git.ikiwiki.info.git] / doc / bugs / underlaydir_file_expose.mdwn

If a file in the srcdir is removed, exposing a file in the underlaydir,
ikiwiki will notice the removal and delete the page from the destdir. The
page from the underlay will not be built. (However, it will be if the wiki
gets rebuilt.)
