+ikiwiki now fails to compile the site, barfing:
+
+ Use of uninitialized value in subroutine entry at /usr/share/perl5/IkiWiki.pm line 1288.
+ ikiwiki.setup: Can't use string ("") as a subroutine ref while "strict refs" in use at /usr/share/perl5/IkiWiki.pm line 1288.
+ BEGIN failed--compilation aborted at (eval 6) line 200.
+
+after forcefully entering the Perl mode of thinking, I reduced this to line
+1285 of IkiWiki.pm (2.53), which apparently returns `undef`:
+
+ my $sub=pagespec_translate($spec);
+
+Why does it even bother parsing the diffs of `recentchanges`?
+
+I have not recompiled this site in ages, so I am not sure when this problem
+was introduced, but it wasn't there when I worked on the site last about
+a year ago in September 2007.
