On c.t.t. there was a discussion about the TeX-ligatures -- and --- for endash and emdash. It seems that the luaotfload/context code fails for some font/mode combination: For some fonts +tlig works with both modes, some works only with mode=base, and there was also a report of font which doesn't work at all (Frutiger LT 55 Roman).
E.g. on my PC +tlig works for Arial (c:/windows/fonts/Arial.ttf) tested with a current context minimals only with mode=base.
\font\test="Arial:mode=node;+tlig"
\font\testb="Arial:mode=base;+tlig"
