    Subject[PATCH] strstrip remove last blank fix
    Hi Pekka,

    strstrip() does not remove the last blank from strings which only consist
    of blanks.

    Example:
    char string[] = " ";
    strstrip(string);

    results in " ", but should produce an empty string!

    The following patch solves this problem:
