 31.17.5 Adjustable Tab Stops
 ----------------------------
 
 This section explains the mechanism for user-specified tab stops and the
 mechanisms that use and set them.  The name “tab stops” is used because
 the feature is similar to that of the tab stops on a typewriter.  The
 feature works by inserting an appropriate number of spaces and tab
 characters to reach the next tab stop column; it does not affect the
 display of tab characters in the buffer (Usual Display).  Note
 that the <TAB> character as input uses this tab stop feature only in a
 few major modes, such as Text mode.  (emacs)Tab Stops.
 
  -- Command: tab-to-tab-stop
      This command inserts spaces or tabs before point, up to the next
      tab stop column defined by ‘tab-stop-list’.
 
  -- User Option: tab-stop-list
      This variable defines the tab stop columns used by
      ‘tab-to-tab-stop’.  It should be either ‘nil’, or a list of
      increasing integers, which need not be evenly spaced.  The list is
      implicitly extended to infinity through repetition of the interval
      between the last and penultimate elements (or ‘tab-width’ if the
      list has fewer than two elements).  A value of ‘nil’ means a tab
      stop every ‘tab-width’ columns.
 
      Use ‘M-x edit-tab-stops’ to edit the location of tab stops
      interactively.
