This controls the width of a TAB character on display.
The value should be a positive integer.
Note that this variable doesn't necessarily affect the size of the
indentation step. However, if the major mode's indentation facility
inserts one or more TAB characters, this variable will affect the
indentation step as well, even if `indent-tabs-mode' is non-nil. */);
