[luatex] nested ifincsname broken in luatex

[David Carlisle]

the following plain tex file

\ifcsname T\ifincsname e\else \hbox{e}\fi X\endcsname\fi
\bye


works in etex/pdftex/xetex but generates an error in luatex (tl2017 pretest)

ifincsname should be true in the implicit csname started by the outer
ifincsname


David


It is perhaps related to this tracker issue about ifincsname in nested
csname, but that one appears fixed,
