Hi Rouslan,
noticed that you might want to have a look at are:
* Since PMA_convertFootnotesToTooltips() now takes a parameter,
you might want to add a PHPDOC header to it to explain what
that parameter is for and that it can be omitted.
* The 'span_id' variable in PMA_convertFootnotesToTooltips() is
now misleading, since it stores a class, not an id.
