This replaces the "TailMatchesN" macros with just "TailMatches", and likewise "HeadMatchesN" becomes "HeadMatches" and "MatchesN" becomes "Matches". The various COMPLETE_WITH_LISTn macros are reduced to COMPLETE_WITH, and the single-item COMPLETE_WITH_CONST also gets folded into that. This eliminates a lot of minor annoyance in writing tab-completion rules. Usefully, the compiled code also gets a bit smaller (10% or so, on my machine). The implementation depends on variadic macros, so we couldn't have done this before we required C99. Andres Freund and Thomas Munro; some cosmetic cleanup by me.
