Latest idea attached.

It's similar to SAFE_FILE_SCANF, but it scanfs each line and first
matching all scanf directives wins and terminates search, otherwise
you get non-zero ret code. For example:

if (SAFE_FILE_LINES_SCANF("/proc/meminfo", "MemFree: %ld", &free))
        tst_brk(TBROK, "Could not parse MemFree");
