There's some stuff in the mode-line that's "global", not particular to that buffer, e.g. date-time-load, org-clock task and erc-track. If
split-window-right, that stuff is both duplicated and truncated in the same way in both windows, e.g. here the org clock task name is truncated (scroll right to see the duplication):
27: 0 U ~/foo.el Top Elisp 12:19 [#ha] [1:31] [Procrast| 99: 0 U ~/foo.el 83% ELisp 12:19 [#ha] [1:31] [Procrast
Is there a way to truncate only the "global" stuff such that I get as much information as possible? E.g.
27: 0 U ~/foo.el Top Elisp 12:19 [#ha] [1:31] [Procras…| 99: 0 U ~/foo.el 83% Elisp 12:19 …tination]
(scroll right to see the non-duplication)
