Infinite loop with directories named "0"

The function common_path_prefix used by tries to test for a
non-empty string by simply relying on "" being considered false.
Unfortunately, the string "0" is also considered false. This results in an
infinite loop when a directory component is named "0".

Basically these two lines:

    $accum1 .= "$tmp1/" if ((defined ($tmp1)) and $tmp1);
    $accum2 .= "$tmp2/" if ((defined ($tmp2)) and $tmp2);

must be replaced with something like this:

    $accum1 .= "$tmp1/" if ((defined ($tmp1)) and $tmp1 ne "");
    $accum2 .= "$tmp2/" if ((defined ($tmp2)) and $tmp2 ne "");
