I am - to fix this I need to at least cache some information as the
file is modified. This will be my next task - improving performance.

If you remove all the tab characters from a file the text widget will
not have any text after a tab character to align with a tabstop, so it
cannot work. That said, it is possible to operate in an environment
where the coding standard mandates spaces: the python plugin that
converts files between the different formats can be told to do this
automatically on loading/saving files (converting from spaces on
loading and to spaces on saving). The tab width setting is taken into
account when doing this.
