Fix a big bug

It took quite a while to find the reason for the bug.
When specifying the '--innerhtml' argument htex only
found the first tag within the in '-a' argument specified
tag. The bug was that the function 'find_closing_tag_pos'
didn't start at the end of the starting tag but at the be-
ginning. Then the level was wrong and blablabla.....
But now it's fixed.
