with empty parentlinks (i.e. on a top level page) the following html is
generated:

<span class="parentlinks">

</span>

which generates a tidy warning:

line 22 column 1 - Warning: trimming empty <span>
An element is empty or only contains white space (newlines, spaces, or tabs). This issue may be the side effect of a tag being implicitly closed by another.

a quick-hack fix is to unconditionally include an   in the parentlinks
span (i guess you could also conditionally put it in there via the parentlinks
plugin, but this would also require modifying the page template).

You can run tidy with --show-warnings no to avoid such warnings. I don't
see any reason to try to make ikiwiki's html avoid all possible tidy
warnings.

hi joey,

fair enough... unfortunately my Html::Template-fu isn't great enough to
know how to filter out that loop entirely in the case of no parent links,
so then i guess i'll have to suck it up and add a manual exception or two,
or at least keep an extra line of diff in my copy of the templates dir :)
