When you have activated a tabulator stop (by using the '\t' character), it might change the colour or the font depending on what or what not you have told it to do. To get the original settings back you can call this function.
It is automatically called when a newline ('\n') is encountered, and in a few other situations.
gstream-set_tab(3), gstream-remove_tab(3), gstream-remove_all_tabs(3)
gstream-remove_all_tabs(3), gstream-remove_tab(3), gstream-set_tab(3).
