Apparently, I need to do
--8<---------------cut here---------------start------------->8---
(defun string=-ic (a b)
"case-insensitive string equality test"
(eq t (compare-strings a nil nil b nil nil t)))
--8<---------------cut here---------------end--------------->8---
I discovered `compare-strings' by noticing that `string-prefix-p'
accepts an IGNORE-CASE argument and looking at its source code.
