[PATCH 8/9] strtok.3: Enable example analysis, fix declaration

[Stephen Kitt <steve@xxxxxxx>]

    for (int j = 1, str1 = argv[1]; ...

declares two variables of type int, j and str1; the pre-existing
char * str1 isn't used. This causes compiler warnings. Declaring j
outside the loop fixes everything.

To enable automated source extraction, separate the text following the
code.
