A comment opens after white space, a tab as well as a space, but the plain scalar terminator checked only for a space before `#`. So `c: d\t#X` kept the tab and hash as content, giving the value `d\t#X` rather than `d` with a trailing comment. Treat a tab before `#` as a space there, in both the lookahead from a white space character and the check on the accumulated value's last character. A tab inside a plain scalar with no `#` after it stays content, and a `#` glued to content with no white space is still content. Raises yaml-test-suite value-level conformance to 187/194 (96.4%) with the parse-level and should-error rejection rates unchanged. 448 tests pass.
