Well 'tput it' returns 8 on my xterm, where it means 'initial tabs'
which is what the "hardware" terminal will by default use unless told
otherwise.  Not sure how to detect current settings since I think the
idea is the application should know what the tab settings are if it
changed them and otherwise they should be what the default settings is.
