Subject: doxygen: assert that the search trie consists only of lowercase data.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~cjwatson/git?a=commitdiff_plain;h=284bac169c34138b86105c59619708e8520d05d3;p=blog.git

doxygen: assert that the search trie consists only of lowercase data.

Can't use `assert c.islower()` as that returns False on non-alnum chars.
Huh.
