+I reverted the `%backlinks` and `$backlinks_calculated` exposing.
+The issue they were solving probably will arise again when I'll work
+on my meta branch again (i.e. when the simplified po one is merged),
+but the po thing is supposed to work without these ugly `our`.
+Seems like it was the last unaddressed item from Joey's review, so I'm
+daring a timid "please pull"... or rather, please review again :)

+
+ * As discussed at [[todo/l10n]] the templates needs to be translatable too. They
+ should be treated properly by po4a using the markdown option - at least with my
+ later patches in [bug#530574](http://bugs.debian.org/530574)) applied.
+
+ * It seems to me that the po plugin (and possibly other parts of ikiwiki) wrongly
+ uses gettext. As I understand it, gettext (as used currently in ikiwiki) always
+ lookup a single language, That might make sense for a single-language site, but
+ multilingual sites should emit all strings targeted at the web output in each own
+ language.
+
+ So generally the system language (used for e.g. compile warnings) should be separated
+ from both master language and slave languages.
+
+ Preferrably the gettext subroutine could be extended to pass locale as optional
+ secondary parameter overriding the default locale (for messages like "N/A" as
+ percentage in po plugin). Alternatively (with above mentioned template support)
+ all such strings could be externalized as templates that can then be localized.
