The Halibut manual contained at least one instance of two index
terms (intentionally) differing only in case, which were being
silently folded into one by the case-insensitive index tag
comparison. Halibut now warns in this situation (but then folds them
anyway, which I think is better than silently generating an index
containing many case-distinct forms of the same word - I imagine
it's very easy to do that by mistake). The manual has been fixed to
explicitly define distinct keywords (in the case I spotted and in
five other cases picked up by the new warning!), and also documents
this issue and how to work with it.
