Most of the time I'll just stick a vim-line at the end of the file as an override, only on an as-needed basis, like that specific file that had way too many levels of nested tabs for its own good. Usually just for displaying purposes, so will shrink the tabstop and set line-numbering to make it easier to find things. Otherwise will just leave the default settings.
