Is the effective default value for titlestring documented somewhere? By effective, I mean the one that displays $(basename) ($(dirname)) (m of n) - GVIM1 or ... ((m) of n), even though titlestring is "actually" empty (so I guess it's some hard-coded default somewhere).
The reason is that I would like to change the m of n part to use the buffer list rather than the argument list (the latter being quite confusing when one frequently uses e.g. :bd), but keep the rest. Yes, I could probably work it out by fully reading the docs on statusline, but I'm trying to avoid that...
maketitlefunction. I'll try and write a VimL version of it. – 3N4N Oct 05 '22 at 18:28
