--- Comment #6 from Fabian Greffrath <fabian+debian at greffrath.com> ---
This code does both directions.

    const size_t namelen = strlen(name);

    if (!strchr(name, '_'))
    {
        // try with interleaved underscores
        int i;
        char *tempname = malloc ((2 * namelen + 1) * sizeof (*tempname));

        tempname[0] = name[0];
        for (i = 1; i < namelen; i++)
        {
            tempname[2*i]   = name[i];
            tempname[2*i-1] = '_';
        }
    }
    else
    {
        // try without interleaved underscores
        int i, j;
        char *tempname = malloc ((namelen + 1) * sizeof (*tempname));

        for (i = j = 0; i < namelen; i++)
        {
            if (name[i] != '_')
                tempname[j++] = name[i];
        }
    }
