Oh right, splitting. Yes right, makes sense. I tried your
console/string, seems good, except the display_split ignores the
padding request? Or did I understand this feature wrongly? I mean, it
slices the string exactly where the end offset is, not by the nearest
" ", space?

Well anyway, I showed it inside sup, seems to be working nicely.

Here's what I did to get it to work, if anybody's interested. I'm in a
rush to work, so there may be mistakes. I tried to check that
everything works.

Summary:
- buffer.rb is patched to slice all strings according to @width, this
fixes issues in inbox-mode when email subjects have wide characters.
Old "hacks" were removed.
- utils.rb is patched to wrap using display_slice and then looking for
nearest space. if no space is found, it uses simply the original
output of display_slice. display_length function defaults to the
display_width

With quick testing for resizing the window with different kind of test
emails, I see no lost characters or text corruption.


Nice, thanks.
