> Hi All,
>
> In Emacs 27.2 the docstring for `tab-width' reads:
>
> "Distance between tab stops (for display of tab characters), in columns. 
> NOTE: This controls the display width of a TAB character, and not the 
> size of an indentation step."
>
> But this seems to contradict to the ubiquitous role in actual 
> indentation the option currently plays.  It is used by `insert-tab' 
> directly.  `tab-to-tab-stop' uses it if `tab-stop-list' is nil, as it is 
> by default.  `indent-relative' may use `tab-to-tab-stop'.  And, through 
> `indent-relative' and `insert-tab', `tab-width' also affects 
> `indent-for-tab-command'.
>
> Am I missing something?  Or is this docstring the remnant of a previous 
> change which was left behind?
>
> Best regards,
> Gustavo.
