I am trying to customise my index, based on this initial question. As i later found out, hyperref and xindy do not play nice if cross references are involved. Which is why I tried to follow this question which disables hyperref for indexin, and builds the links itself from the style file.
While I have some issues with the stylefile and links not working that is another question.
I am interested in why my formatting breaks: I would like pagenumbers to be right aligned, which they are except for the last entry of every lettergroup where the line extends slighlty more to the right.
Why is that/how do I fix this? (I assume i might do things incorrectly in the markup-letter-group at the bottom of the xindy file, as that is the homebrew part)
