when read rich or phonetic with EOF,then read it at next continue

[gr258]

In get_string function,when read rich or phonetic with EOF,the w.continue_rich and w.continue_apsb are not correct,it shout sub read count,then read the left count at next continue stream.

I dont't think this patch is acceptable, you can add your change but you can't remove the other feature like removing ver5 support and others

make sure just add something and don't affect others.

I dont't know the meaning of "removing ver5 support".In the first "else" branch, the w.Is5ver is false, so the next "if w.Is5ver " is a dead code,that's why i remove this condition.

code: if w.Is5ver { var bts = make([]byte, size) _, err = buf.Read(bts) res = string(bts) } else { ...... if w.Is5ver { seek_size = int64(2 * richtext_num) } else { seek_size = int64(4 * richtext_num) } ......
