    * src/buffer.c (mode-line-format): Remove docs for obsolete %t construct
    
    This documentation had been previously removed in 1999 in [1]
    but was subsequently restored again in a different form in 2006
    in [2] as the construct was still supported on some systems.
    However it looks like it hasn't done what that documentation
    indicated since [3] in 2011, and the final remnant of this
    functionality was removed in [4] in 2013; so it seems clear that
    it's no longer supported and shouldn't be documented now.
