skipSeparation consumed only spaces between tokens, so a tab after an indicator leaked into the following node: an explicit key written `?\tkey` became the key `\tkey` rather than `key`. A tab is separation white space in YAML, forbidden only as indentation, which the line-start scan already handles before this point. Skip tabs there too. This closes the post-indicator tab leak left open when the indicator boundary itself was changed, and handles a run of tabs between a `:` and its value. The test-suite rates are unchanged, since no comparable case isolates this, but the parser now matches the spec on tab separation. 435 tests pass.
