[dev-context] --iftouched not working

Hi, mtxrun --iftouched does not work. The reason is that line 147000 of mtxrun.lua has local oldname, newname = string.split(touchname, ",") This sets oldname to be equal to a table and newname to nil. Consequently, the next test if oldname and newname and oldname ~= "" and newname ~= "" then fails. An easy fix is to wrap string.split inside a unpack. local oldname, newname = unwrap(string.split(touchname, ",")) but there might be more canonical ways of fixing this. Aditya
