This is actually clearer to read IMO, and is probably how I would code it if
I ever wanted such a test.

Indeed.  And so why don't we wrap up this too-long discussion this way?:
1. *Document* that string comparisons against headers MUST NOT match absent headers. 2. *Document* that the preferred way to test for a header that is either empty or absent is as Ned wrote above.
3. Move on.
