Use of separators in Execute operation

Execute -operation might be strict with the path separators. If wrong
separators are used the Execute -operation might fail. Fixed so that
Execute -operations paths are saved to dat file without converting to
normalized separators. As the target dir is saved as @RELOCATABLE_PATH@
also for Execute -operation, check from the next available separator
which separator should be used for operation.
