This fixes several latent bugs where code went down the path
with double buffering enabled when it wasn't, and vice versa.
* src/xfns.c (x_set_inhibit_double_buffering): Improve
commentary and only define when HAVE_XDBE.
(x_mark_frame_dirty): Only set buffer flip flag when HAVE_XDBE.
(initial_set_up_x_back_buffer): Clean up coding style and remove
unnecessary block_input pair.
(Fx_double_buffered_p): Always return nil if !HAVE_XDBE.
(x_frame_parm_handlers): Don't set double buffering handler if
!HAVE_XDBE.
* src/xftfont.c (xftfont_drop_xrender_surfaces, xftfont_driver):
Only define when XDBE is available.
* src/xterm.c (x_drop_xrender_surfaces): Likewise.
(x_clear_window): Don't test double buffering flags when
!HAVE_XDBE.
(show_back_buffer): Only define when HAVE_XDBE.
(x_flip_and_flush): Don't try to flip when !HAVE_XDBE.
(XTframe_up_to_date): Likewise.

available.

(eshell-pred-substitute, eshell-join-memebers, eshell-split-members):
... and use them here.
(eshell-include-members): Pass 'mod-char' and use
'eshell-get-delimited-modifier-argument'.
