[Dev-luatex] Can't find file without extension

Hi, I just tried the following: mpg@siegel:~% echo '\\bye' > foobar mpg@siegel:~% pdftex foobar This is pdfTeXk, Version 3.1415926-1.40.9 (Web2C 7.5.7) %&-line parsing enabled. entering extended mode (./foobar ) No pages of output. Transcript written on foobar.log. mpg@siegel:~% luatex foobar This is LuaTeX, Version snapshot-0.25.4-2008071722 (Web2C 7.5.7) ! I can't find file `foobar.tex'. <*> foobar Please type another input file name: Looks like luatex doesn't want to eat files without extensions, while pdftex accepts them. Is it a feature? Manuel.
