There is a novelty in this new version that I don't think we discussed
before: automatic expansion of tabs to 8 hard space characters. That
number should not be hardcoded as there is no reason to believe a tab
character always expands to 8 space characters. You should check
the environment first; if not present the default expansion number should
be a symbolic constant as opposed to a magic number sprinkled all over the
places. I would also encourage you to introduce more abstraction to
reduce the size of diagnostic_show_locus.
