eintr: Indent Tabs Mode
16.6 Indent Tabs Mode
=====================
By default, Emacs inserts tabs in place of multiple spaces when it
formats a region. (For example, you might indent many lines of text all
at once with the ‘indent-region’ command.) Tabs look fine on a terminal
or with ordinary printing, but they produce badly indented output when
you use TeX or Texinfo since TeX ignores tabs.
The following turns off Indent Tabs mode:
;;; Prevent Extraneous Tabs
(setq-default indent-tabs-mode nil)
Note that this line uses ‘setq-default’ rather than the ‘setq’
command that we have seen before. The ‘setq-default’ command sets
values only in buffers that do not have their own local values for the
variable.
