I write a function for this.

/*
 * Make list of items easy for l10n translation.
 *
 *   1. Input list of items one by one through the 2nd argument,
 *      but leave the 1st argument as NULL.
 *
 *   2. Get the output joint string from the 1st argument.
 *
 * According to the number of items input. The joint string maybe:
 *
 *   a
 *   a and b
 *   a, b and c
 *   a, b, c and d
 *
