There's probably a solution to this, but it could be a lot of work for a
small benefit.

If emacsclient --eval could pass in the stdin/stdout/stderr from the
terminal to the daemon, then things would work as I expect. But the
work-around is easy: emacsclient -c -e '...'

However, I noticed that stderr appears to be available, when there's an
error:

$ emacsclient --eval '(man fprintf)'
*ERROR*: Symbol’s value as variable is void: fprintf

and also when it works properly:

$ emacsclient --eval "(list-buffers)"
#<window 194 on *Buffer List*>
