I don't really know at this stage, but I think part of the problem lies

defun find-tag-tag (string)

which seems to reserve a significant use for the colon. I'll have to
invest time in trying to understand at least a little of what etags.el
does, but as that file's commentary puts it, "The namespacing of this
package is a mess:". I agree.
