Dear emacs developers, Juri, per default tab-bar uses buffer
names as tab labels. But these might be very looong:

Please provide an option to dynamically shorten at least
automatic tab labels in order not to overflow the tab bar into
another line OR provide an option with sensible default for the
max length of automatic tab labels (e.g. 23 characters per tab
label would allow for at least 3 tabs on a 80 char terminal) OR
something to such effect.
Thanks, Gregor

I've never seen that long buffer name before.
This reminds Guinness Book record for the longest name :)

Maybe such a new option:
(defcustom tab-bar-tab-name-max 23
and using it on the default values of tab-bar-tab-name-current,
tab-bar-tab-name-current-with-count, tab-bar-tab-name-all?

yes, this would be helpful for me.

I'm still not sure whether to use the new option in all functions above,
or add a new function that truncates the name. It seems the latter is
better:

The same option should be added also to tab-line to truncate tab-line
tab names. Currently I fixed a bug that occurred when a tab name
was longer than window width. With such an option set to some reasonable
default value this situation won't happen.
