I should have been more explicit about the point of this bug report,
which is this: when I invoke `emacsclient -c' under X11, I expect the
usual behavior under X11, but in the above case, --daemon apparently
circumvents this behavior.

I cannot tell from the current documentation when using --daemon has
this effect and when it doesn't.  Hence I cannot tell whether this is a
bug or a limitation of the current implementation.  So I hope this and
similar bug reports lead to both more complete documentation and either
a bug fix or, at some point, a more feature-rich implementation.
