+Problem with [[plugins/map]]:

+# Observed behavior:

+
+Note that you get "blog" and "tags", and they're both links, but "life" and "tech" are not links.

+
+Note that you you don't get "blog" or "tags", and "life" and "tech" are links now.

+(Disclaimer: I don't know ikiwiki internals.)
+
+Map tries to calculate a "common prefix" between the pagespec and the page being rendered, and then later does some substitutions using the prefix. But the path has /'s in it and the common prefix doesn't, so it never matches correctly. So, add the /'s.
