Comment (by BigBrownChunx):

 Oh, I just noticed the log10 bit.  Is that necessairy to have that in
 there since the sscanf already has a ; in it?  Would it be better to have
 {{{
 else if(*(text+1) == '#' && ((sscanf(text, "&#%u;", &pound) == 1) ||
                         (sscanf(text, "&#x%x;", &pound) == 1)) &&
                         pound != 0) {
 }}}
