Which could be fixed by (modify-category-entry ?’ ?l).
I would suggest this additional docstring patch, because I was confused
at first as to what CATEGORY was supposed to be (I looked around a bit
for how to create some kind of "category object"):
diff --git i/src/category.c w/src/category.c
index 4397f66..31ac2ec 100644
--- i/src/category.c
+++ w/src/category.c
@@ -336,6 +336,7 @@ DEFUN ("modify-category-entry", Fmodify_category_entry,
the current buffer's category table.
CHARACTER can be either a single character or a cons representing the
lower and upper ends of an inclusive character range to modify.
+CATEGORY must be a category name (a character between ` ' and `~').

then delete CATEGORY from the category set instead of adding it. */)

Right, but I think this bug is about the user modifying stuff.
