page_parser file naming

[Olivier Doucet]

Tool page_parser has a curious way to name page files. As stated in documentation (http://www.percona.com/docs/wiki/innodb-data-recovery-tool:mysql-data-recovery:extracting_the_desired_pages) :
pages-1301110359/0-52/
pages-1301110359/0-52/216-00000216.page
pages-1301110359/0-52/70-00000216.page
"The file 70-00000216.page was read before the file 216-00000216.page; this physical ordering can be important to preserve."

I wondered why page files are not named like this :
pages-1301110359/0-52/00216-00000216.page
pages-1301110359/0-52/00070-00000216.page

It is easier to order this way and modification is very easy : just change sprintf format to use "%08lu" instead of "%lu"

    175 if(is_index){
    176 sprintf(file_name, "%s/%08lu-%08lu.page", dir_name, id++, page_id);
    177 }

If there is an other cause of this naming, sorry for the disturbance.
