I think echo/echon is doing fine. It's getchar() that's eating up
trailing spaces. Compare @a's for:
:redir @a | echon " 123 " | call getchar() | redir END
:redir @a | echon "\n123 " | call getchar() | redir END
:redir @a || echon " 123 " | call getchar() | redir END
Not sure what the last example is supposed to do.
The "\n" or previous ex command "|" has something to do with it.

It's odd that it remembers all the trailing spaces, and prints them
out as soon as the echon following the getchar() prints a
non-space char.
I'm thinking that it could also be the rendering in the command window
that is causing it, as if it truncates trailing spaces when writing to
the screen, but not when actually building the strings internally.
It's probably a combination of this, and that getchar() isn't in
the list of things that triggers printing the trailing spaces.
I can't tell whether to call this a bug yet.
