Stupidly, I started doing this today:
(setq mode-line-end-spaces (make-string 1024 ?─))
It makes the modeline look prettier (except when it doesn't).
The 1024 is arbitrary, it replaces %- (infinite MINUS HYPHEN).
I can't see how to ask for infinity of an arbitrary codepoint.
I want to do the same thing for the vertical-border character,
which is "|" for me (my window-system is nil).
Where do I set that?
CAN I set that?
I tried apropos-variable and apropos-value and grepping lisp/ and src/,
but my fu is weak.

What's wrong with 1024? If that might be too few, enlarge it.

I hope by "do the same thing" you do NOT mean to have 1024 characters
as the border, but rather replace "|" with some non-ASCII character.

It hides in one of the extra slots of the display table. See the node
"Display Tables" in the ELisp manual.
> CAN I set that?
Yes, something like
(set-display-table-slot (setq standard-display-table (make-display-table))
'vertical-border ?│)
But beware: the character you use must be encodable by your
terminal-coding-system, otherwise you will get a question mark "?"
instead of your fancy character.
(Personally, I question the utility of doing what you want, but that's
me.)

It works; it just feels inelegant compared to %-.

Ah, thanks -- I found disp-table but from reading it I thought it was
only used for M-x list charset chars RET, and (make-display-table)
didn't use a "|" as its default vertical-border, which fooled me.

This works for me:
(set-display-table-slot standard-display-table 'vertical-border ?│)

Understood; thus the "Stupidly" at the start of my email.
Anywhere modern enough that I have Emacs and dotfiles installed,
bloody well ought to be UTF-8 throughout, so I'm not to worried.
If it annoys me I'll just turn it off again.
It already looks funny in DejaVu Sans Mono at certain :pixelsize's,
because the hinter makes the "ends" of each char a bit fatter, so you
end up with a fuzzy pulse. Oh well.

The default value of standard-display-table is nil.

Not every "modern enough" environment will be able to do that on a
TTY.

That's what I meant when I questioned the utility of this.

Waah, I ran into a problem.
Vertical split switches back to using '|' character in at least one mode:
when rcirc is the left window in the split.
Looks like rcirc has a buffer-local disp-table so that it can show the
little arrow in the fringe (or over the top of text, in the tty) to show
where evaluation is up to.
So now I'm up to
(setq mode-line-end-spaces (make-string 1024 ?─))
(set-display-table-slot standard-display-table 'vertical-border ?│)
(add-hook 'rcirc-mode-hook
(λ ()
(set-display-table-slot buffer-display-table 'vertical-border ?│)))

These facilities are indeed intended for specialized modes and
commands, not for users.
