This commit adds useful information to the "tag mismatch" warning.

Basic tests:

#pragma warning disable 203
#pragma warning disable 204

[Y-Less]

Should but found "_" be but found none? It isn't always obvious that no tag is _:. Or maybe but found none ("_").

[YashasSamaga]

What if the user had explicitly mentioned the tag to be _:? Found none wouldn't make sense in this context.

none ("_") is sort of fine though.
