Without this, the 'i' variable declared before could be overridden by accident, e.g. for i in "${@}"; do __ksft_status_merge "${i}" ## 'i' has been modified foo "${i}" ## using 'i' with an unexpected value done After a quick look, it looks like 'i' is currently not used after having been modified in __ksft_status_merge(), but still, better be safe than sorry. I saw this while modifying the same file, not because I suspected an issue somewhere.
