[aprssig] The Current Meaning of WIDEn-N (incorrect -again)

Neither is true.  It is not the level, nor is it a sum of anything.  The
"n" is the original value of "N".  Except in the "special case" of
"WIDE2-1" where it is simply a "special case" to achieve 1 hop without
triggering local "WIDE1-1" digis.

So which one is it? You just said that the first number doesn't
differentiate between wide and fill-in digis, and also doesn't indicate
the total number of hops requested from the original user. I thought you'd
at least completely agree with Stephen's second statement.
