Curious Case of MENTHOL -- Testing Stitcher Limits

[grishagin]

Some Inxgith MENTHOL entries merged a few quite unrelated entries from Rancho (and, perhaps, elsewhere).
For example, these two have the same Targets and Conditions, which are coming from different menthol entries.

Now, interestingly, the mixture of "everything MENTHOL" (MENTHOL, UNSPECIFIED FORM) does not have any of these annotations.
