I noticed a strange regression related to header API when migrated from 7.84
to 8.5.0, and I see the same issue in TOT branch. The issue is that the
header API returns '\r' as a header value when some service returns a header
with no value (like: hdr: \r\n).
The 7.84 returns expected empty string in such cases. Is a bug or some
behavior change?
I could not spot when this broke. To me it looks like the logic was always
wrong (and the test case did not verify blank header content):
