Thanks. You won't believe it but yesterday this would have saved me
half an hour poking around with this. Until then I didn't know that
'recenter' is now our moral equivalent of 'redisplay'.
You might also reconsider the Elisp manual entry where it says
If this variable is non-=E2=80=98nil=E2=80=99, the tool bar automat=
ically resizes
to show all defined tool bar items=E2=80=94but not larger than a qu=
arter of
the frame=E2=80=99s height.
I've been digging through Gerd's and Kim's rewrites of
'redisplay_tool_bar' and nowhere found a reference to that "quarter".
Did that ever work and when?

I stumbled across this feature because wrapping and unwrapping the tool
bar on Motif by changing the frame width shrinks the frame height for
inexplicable reasons until it is down to a few lines. Lucid and
non-toolkit builds do not have this issue. Currently, I just try to
understand the design considerations and whether they are responsible
for the behavior I see.

With emacs -Q run a graphical build with a tab bar or an internal tool
bar (motif, lucid, no toolkit have the latter). Do
(setq auto-resize-tab-bars 'grow-only)
and/or
(setq auto-resize-tool-bars 'grow-only)
Now make the frame very narrow so the tool and/or tab bar wrap(s)
around. Expand the frame again, so the items on the bar(s) occupy one
line only. You will see empty lines below the lines showing the items.
According to the doc-strings of the above options and the Elisp manual
you should now be able to use 'recenter' to get rid of these empty
lines:
If value is =E2=80=98grow-only=E2=80=99, the tab-bar=E2=80=99s height =
is only increased
automatically; to decrease the tab-bar height, use M-x recenter.
However, this doesn't work by default since in the following part of
'recenter'
if (!NILP (redisplay)
&& !NILP (Vrecenter_redisplay)
&& (!EQ (Vrecenter_redisplay, Qtty)
|| !NILP (Ftty_type (selected_frame))))
{
ptrdiff_t i;
/* Invalidate pixel data calculated for all compositions. */
for (i =3D 0; i < n_compositions; i++)
composition_table[i]->font =3D NULL;
#if defined (HAVE_WINDOW_SYSTEM)
WINDOW_XFRAME (w)->minimize_tab_bar_window_p =3D 1;
#endif
#if defined (HAVE_WINDOW_SYSTEM) && ! defined (HAVE_EXT_TOOL_BAR)
WINDOW_XFRAME (w)->minimize_tool_bar_window_p =3D 1;
#endif
Fredraw_frame (WINDOW_FRAME (w));
SET_FRAME_GARBAGED (WINDOW_XFRAME (w));
Vrecenter_redisplay is by default 'tty' and Ftty_type (selected_frame)
is nil, so the conjunct never becomes true and minimize_tab_bar_window_p
is never set to 1.
So we'd have to mention in the docs of this option that one can regain
these lines only by setting 'recenter-redisplay' to anything but the
default. Better IMHO would be to abolish the never used and completely
useless 'grow-only' value for these options.
