$ LD_LIBRARY_PATH= $ LD_LIBRARY_PATH="/foobar${LD_LIBRARY_PATH+":$LD_LIBRARY_PATH"}" $ echo $LD_LIBRARY_PATH /foobar:LD_LIBRARY_PATH can be unset "naturally", ie without the user knowing. It is actually the default. However, if it evaluates to the empty string it comes from the environment, ie the user set it like that. We can't blame texmacs for that, it is the user's fault.So, I think we don't have to handle this case.
We do. ld.so treats empty LD_LIBRARY_PATH and unset LD_LIBRARY_PATH equally (i.e. it doesn't add anything to search path) and so should do texmacs.
