Fix flushing bug in tui_puts_internal
A while back I changed gdb not to flush in some places. It turned out
that this broke the TUI a little. An easy way to see it is to run
"gdb -tui -nx", then "file gdb" at the gdb prompt. gdb will print the
usual "Reading symbols..." message -- but it won't appear on-screen
until the reading is complete.
This patch changes the TUI to do the equivalent of line buffering in
tui_puts_internal.

* tui/tui-io.c (tui_puts_internal): Call wrefresh if newline is
seen.
