Yes and no.  The behavior could be similar to what we do with
`completion-ignored-extensions` (where those files are only ignored if
there are others), e.g. for an input "i" we'd list ("icomplete"
"image" ...)  but for an input "icomplet" we'd list
("icomplete.el" "icomplete.elc" "icomplete.el.BAK").
