2020-07-31shell: Fix "read -d ''" behaviorChristian Eggers
With bash's read builtin it is possible to read from a file (e.g. device-tree) until the first '\0' character: IFS= read -r -d '' VARIABLE < file In busybox ash the -d extension is also implemented, but checking the read character for '\0' has to be performed after comparing with the delimiter.
