Support auto-detecting font style
We now support XeTeX's syntax, try:
\input luaotfload.sty
\font\termesr ={TeX Gyre Termes:+liga} at 10pt
\font\termesb ={TeX Gyre Termes/B:+liga} at 10pt
\font\termesi ={TeX Gyre Termes/I:+liga} at 10pt
\font\termesbi={TeX Gyre Termes/BI:+liga} at 10pt
\font\termesib={TeX Gyre Termes/IB:+liga} at 10pt
\termesr What a nice day fi fl ffi ffl ff\par
\termesb What a nice day fi fl ffi ffl ff\par
\termesi What a nice day fi fl ffi ffl ff\par
\termesbi What a nice day fi fl ffi ffl ff\par
\termesib What a nice day fi fl ffi ffl ff\par
