That of 'recenter' does.  But since these options do not work out of the
box (a user has to customize the option 'recenter-redisplay' too), it
would be useful if the docs of 'auto-resize-tool-bars' and
'auto-resize-tab-bars' told so.  At the moment they just tell me to use
M-x recenter or C-l.  Also, the doc string of 'recenter' does not
mention the tab bar and its Elisp manual entry mentions neither the tab
nor the tool bar.

We could stop mentioning 'grow-only' in the doc-strings and manuals and
leave it in as an undocumented feature.
