Plain scalar line folding strips white space around continuation lines, but the scanner stripped only spaces, so tabs leaked in. A tab is not indentation, so the indentation scan left a continuation line's leading tab in place and it joined the value (`\t3rd` folded as `\t3rd`, not `3rd`), and a line of only white space holding a tab (` \t`) was treated as a non-blank continuation, folding to a space rather than the line break an empty line gives. Skip leading white space, tabs included, before a continuation line's content, and treat a whitespace-only line that holds a tab as blank when counting the folded line breaks. Raises yaml-test-suite value-level conformance to 183/194 (94.3%) with the parse-level and should-error rejection rates unchanged. 441 tests pass.
